The sine of the compound angle ninety degrees plus theta is equal to the value of cosine of angle theta. $\sin{(90^\circ+\theta)}$ $\,=\,$ $\cos{\theta}$ Usage. It is used as a formula in trigonometry to convert the sine of a compound angle ninety degrees plus an angle in terms of cosine of angle. Example. Evaluate $\sin{135^\circ}$45 degrees plus or minus 360 degrees and 135 degrees plus or minus 360 degrees. you can graph the equation of y = csc(x). since you can't do that directly, then you need to graph the equation of y = 1/sin(x). since most graphing software graphs trigonometric functions in radians, you need to convert 45 degrees and 135 degrees to radians.What is the value of #sin -45^@#?

This online trigonometry calculator will calculate the sine, cosine, tangent, cotangent, secant and cosecant of angle values entered in degrees or radians. The trigonometric functions are also known as the circular functions.We would like to show you a description here but the site won’t allow us.Solution: Since, we know that sin is positive in the 1st and 2nd Quadrant, here, 135° lies in the 2nd Quadrant, then. By the Trigonometric Identity of Supplementary Angles, We know that sin (180° – θ) = sin θ. Hence, sin 135° = sin (180° – 45°) = sin 45° {As given by Identity} = 1/√2.Precalculus. Convert from Degrees to Radians sin (135) sin(135) sin ( 135) To convert degrees to radians, multiply by π 180° π 180 °, since a full circle is 360° 360 ° or 2π 2 π radians. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. sin(45)⋅ π 180 sin ( 45) ⋅ π 180 radians.c² = b² + a²(sin(γ)² + cos(γ)²) - 2ab × cos(γ) As a sum of squares of sine and cosine is equal to 1, we obtain the final formula: c² = a² + b² - 2ab × cos(γ) 3. Ptolemy's theorem. Another law of cosines proof that is relatively easy to understand uses Ptolemy's theorem: Calculate the value of the sin of 1.3 ° To enter an angle in radians, enter sin(1.3RAD) sin(1.3 °) = 0.0226873335727814 Sine, in mathematics, is a trigonometric function of an angle. We use sin, cos, and tan functions to calculate the angles. The degrees used commonly are 0, 30, 45, 60, 90, 180, 270 and 360 degrees. We use these degrees to find the value of the other trigonometric angles like the value of sine 15 degrees. What is the value of Sin 15°? The actual value of sin 15 degrees is given by: Free math problem solver answers your algeSin 135 Degrees. Trigonometry is a branch of mathematics that deals wi Explanation: For sin 105 degrees, the angle 105° lies between 90° and 180° (Second Quadrant ). Since sine function is positive in the second quadrant, thus sin 105° value = (√6 + √2)/4 or 0.9659258. . . Since the sine function is a periodic function, we can represent sin 105° as, sin 105 degrees = sin (105° + n × 360°), n ∈ Z.Convert to Rectangular 2(cos(135)+isin(135)) Step 1. Simplify each term.

Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. As given, sin (90° +30°) = cos 30°. It means that sin 120° = cos 30°. We know that the value of cos 30 degrees is √3/2. Our cotangent calculator accepts input in d

Explanation: For sin 42 degrees, the angle 42° lies between 0° and 90° (First Quadrant ). Since sine function is positive in the first quadrant, thus sin 42° value = 0.6691306. . . ⇒ sin 42° = sin 402° = sin 762°, and so on. Note: Since, sine is an odd function, the value of sin (-42°) = -sin (42°).135: 180: 2x: 0: 90: 180: 270: 360: sin 2x: 0: 1: 0 -1: 0: Plot the points and join with a smooth curve. Graphing basic sine and cosine functions (in degrees) Show Video Lesson. Graphing basic sine and cosine functions (in radians) How to graph sine and cosine from the unit circle and from a table of valuesFind exact value of sin (105) Ans: (sqrt(2 + sqrt3)/2) sin (105) = sin (15 + 90) = cos 15. First find (cos 15). Call cos 15 = cos x Apply the trig identity: cos 2x = 2cos^2 x - 1. cos 2x = cos (30) = sqrt3/2 = 2cos^2 x - 1 2cos^2 x = 1 + sqrt3/2 = (2 + sqrt3)/2 cos^2 x = (2 + sqrt3)/4 cos x = cos 15 = (sqrt(2 + sqrt3)/2. (since cos 15 is positive) sin (105) = cos (15) = sqrt(2 + sqrt3)/2 ...sin (150°) = sin (30°) sin (150°) = 1/2 So the exact value of sin 150° is 1/2. Similar Questions.
