Question

what is the value of or formula of
1-cos theta =?
​

Answer 1

Answer:

sin(theta) = a / c csc(theta) = 1 / sin(theta) = c / a

cos(theta) = b / c sec(theta) = 1 / cos(theta) = c / b

tan(theta) = sin(theta) / cos(theta) = a / b cot(theta) = 1/

Answer 2

1 - cosx = 2 sin^2 (x/2)
This is the formula of 1 - cosx
I take theta as x
