Question

which are defactorization formulae in trigonometry give me list of formulae.

Answer 1

Sin theta = P/H = perpendicular/Hypotenuse

Cos theta = B/H = Base/ Hypotenuse

Tan theta = P/B = Perpendicular/Base

Sec theta = H/B = Hypotenuse/Base

COSEC theta = H/P = Hypotenuse/Perpendicular

Cot theta = B/P = Base/Perpendicular

Sin² theta + Cos² theta = 1

Tan² theta - Sec² theta = 1

Cosec² theta - Cot² theta = 1.

Tan theta = 1/Cot theta

Cot theta = 1/Tan theta

Sin theta = 1/Cosec theta

Cosec theta = 1/Sin theta

Cos theta = 1/Sec theta

Sec theta = 1/Cos theta
