Question

Prove Cos
[tex] \cos(?) \times \tan(?) = \sin(?)

Answer 1

To prove :- Cos∅ × tan∅ = Sin∅

Solution :-

since , tan∅ = sin∅/Cos∅

Taking LHS

Cos∅ × tan∅

cos∅ × Sin∅/cos∅

= Sin∅

LHS = RHS [ Hence proved ]

Answer 2

The answer is given below :

Now, L.H.S.

$= cos \alpha \times tan \alpha \\ \\ = cos \alpha \times \frac{sin \alpha }{cos \alpha } \\ \\ = sin \alpha$

= R.H.S. [Proved]
