Answer:
yes sinA/ cosA is tanA th8s is the one of the formula
Answer
Proved!
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
Divide sin A by cos A = BC/AB/[AC/AB] = [BC/AB]*[AB/AC] = BC/AC = (altitude or opposite)/(base or adjacent)
tan A = (altitude or opposite)/(base or adjacent), same as BC/AC which is
sin A /cos A.
Hence tan A = sin A /cos A. Proved
