Question

prove tan theta = sin theta/cos theta
​

Answer 1

Step-by-step explanation:

tan∅

√sec²∅-1

√(1/cos²∅)-1

√(1-cos²∅)/cos²

√sin²∅/cos²∅

√(sin∅/cos∅)²

sin∅/cos∅

hence proved

#666

Answer 2

Answer:

Answer

1st Method : sin∅/cos∅=tan∅

Take ∅=0. sin 0/cos0. =0/1. =0=LHS. tan 0. ...

2nd method: Draw a right-angled triangle ABC. Name AB as the base or adjacent, CB as the altitude or opposite, AB as hypotenuse and right angle at C. sin A = BC/AB and cos A = AC/AB.
