Question

Prove it =


(cosA /cotA = sinA )​

Answer 1

LHS=

b/h ÷b/p

b/h × p/b

p/h =Sin A

RHS proved

Explanation:

Sin= p/h

cos= b/h

cot= b/p

in the second step we did reciprocal formula where ÷ sign will turn into × sign and b/h will turn into p/h. now we can do cancel b and b

now the answer is p/h
