Question

What is the value of the cos(900°) is the value of cos (900°)

Answer 1

Answer:

Just see how many 360s are there in the theta value. Here 900/360 gives 2 point something. This means after 360*2=720 degrees. Subtract this from 900 and you get 180 degrees. This means 900 degrees is actually just 180 degrees, only that it completes 2 circles.

Cos900=cos(2π+π)=cosπ=-1

Tip: When doing trigonometry, remember that 360 degrees is equivalent to 0 degrees
