Question

The equation of the line which cuts off the intercepts 2a\sec \theta
and 2a\,\text{cosec}\,\theta
on the axes is
A) x\sin \theta +y\cos \theta -2a=0 B) x\cos \theta +y\sin \theta -2a=0 C) x\sec \theta +y\,\text{cosec}\theta -2a=0 D) x\,\text{cosec}\theta +y\sec \theta -2a=0

Answer 1

If this property is applied to the trigonometric functions, the following equations will be ... \begin{align*}\sin(\sin^{-1 }(x)) = x && \cos(\cos^{-1}(x)) = x && \tan ...
