**How to work out the values of sin cos and tan for 30° 45**

Sine, cosine, and tangent all assume you have a right triangle (where one angle is 90 degrees). Each function operates on one number, which represents another angle (call it x) in the triangle.... Step 5(orange):Once you have values for sine function, invert them for cosine i.e( sin 90 = cos 0, sin 60 = cos 30, sin 45 = cos 45 and so on) and you get values for cosine function. Step 6: For tangent, put sin/cos values and simplify.

- The average value of a whole sinusoidal waveform over one complete cycle is zero as the two halves cancel each other out, so the average value is taken over half a cycle. The average value of a sine wave of voltage or current is 0.637 times the peak value, (Vp or Ip. This mathematical relationship between the average values applies to both AC current and AC voltage. Sometimes it is required to
- 23/07/2008 · The sine function takes a real number (i.e., radians, which are real numbers) as input, and evaluates to a real number. If you are using a calculator and are asked to find the sine of 56 degrees, then your calculator needs to be in degree mode. If you are asked to find the sine of an arbitrary real number, as you are in this problem, the calculator needs to be in radian mode.
