Sin 135 degrees.

1 Answer. Dylan C. Feb 17, 2015. Converting from degrees to radians is actually very simple, it is a one step unit conversion. All we need to know to solve this is that (π)radians = (180)degrees. Therefore 135degrees ⋅ (π)radians 180degrees = (135 180)π radians = 3π 4 radians. Answer link. Converting from degrees to radians is actually ...Find the value of cos 135 °: Since, cos 135 ° = cos (90 ° + 45 °) Which clearly lies in the 2 n d quadrant, where cos is negative. since c o s (90 ° + θ) =-sin θ. Thus, cos 135 ° = cos (90 ° + 45 °) =-sin 45 ° sin 45 ° = 1 2 =-1 2. Hence, the value of cos 135 ° is -1 2.To solve for sin(-135), the reference angle will be obtained as follow: sin(-135) =-sin(135) =-sin(180-135) =-sin 45 hence the reference angle θ=45° Use the steps to determine the exact value of sin(−135)°.This simplifies to option (a) The sine of 27 degrees divided by P equals the sine of 135 degrees divided by 9.5, which is the correct answer.To summarize, for triangle PQR, where angle at P is 27°, angle at R is 135°, and side R measures 9.5, using the Law of Sines we can say:P = sin(27°) * 9.5 / sin(135°) to find the length of side P.

In trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign may vary). So for example sin(45) = 0.707. The angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator: sin(135) = 0.707Write the complex number in polar form. Express the argument in degrees. 4i A. 4(\cos 0 degree + i\sin 0 degree) B. 4(\cos 270 degrees + i\sin 270 degrees) C. 4(\cos 90 degrees + i\sin 90 degrees) D. Write a function to convert a rectangular form of a complex number into its polar form using the Euler identity.

For sin 170 degrees, the angle 170° lies between 90° and 180° (Second Quadrant ). Since sine function is positive in the second quadrant, thus sin 170° value = 0.1736481. . . Since the sine function is a periodic function, we can represent sin 170° as, sin 170 degrees = sin (170° + n × 360°), n ∈ Z. ⇒ sin 170° = sin 530° = sin 890 ...

Rewrite the angle, using the special angles from right triangles. One way to rewrite 135 degrees is 90 degrees + 45 degrees. Choose the appropriate sum or difference formula. Plug the information you know into the formula. Therefore, a = 90 degrees and b = 45 degrees. Use the unit circle to look up the sine and cosine values you need.299.
