(d)/(d theta){tan^(-1)((1-cos theta)/(sin theta))}" equals "

The value of tan^(-1)((x cos theta)/(1-x sin theta))-cot^(-1)((cos theta)/(x-sin theta)) is 2 theta(b)theta (c) (theta)/(2)(d) independent of theta

(sin theta)/(1+cos theta) is equal to (1+cos theta)/(sin theta)(b)(1-cos theta)/(cos theta)(c)(1-cos theta)/(sin theta) (d) (1-sin theta)/(cos theta)

int_(0)^((pi)/(2))(cos theta-sin theta)/((1+cos theta)(1+sin theta))d theta equals -

(sin theta tan theta)/(1-cos theta)=1+sec theta

A simplified of ((Sin theta)/(1+cos theta)+(1+cos theta)/(sin theta))(1/(tan theta+cot theta)) is: ((Sin theta)/(1+cos theta)+(1+cos theta)/(sin theta))(1/(tan theta+cot theta)) का सरलीकृत मान ज्ञात करें |

1-(sin^(2)theta)/(1+cos theta)+(1+cos theta)/(sin theta)-(sin theta)/(1-cos theta) equals

(sin theta)/(1-cot theta)+(cos theta)/(1-tan theta) is equal to (a) 0 (b) 1(c)sin theta+cos theta(d)sin theta-cos theta

If f(theta) = sin(tan^(-1)(("sin theta)/(sqrt(cos 2 theta)))) , where -pi/4 lt theta lt pi/4 , then the value of d/(d(tan theta)) f(theta) is
