Question

if sin theta = a/ root a^2 + b2 then find value of all trigonometric ratio

Answer 1

Answer:

As it is given that,

Sin∅=a/√a²+b²=opposite/hypotenuse

Use Pythagoras theorem,

Hy²=S²+S²

a²+b²=a²+S²

s²=b²

S=b

Cos∅=b/√a²+b²

Tan∅=a/b

Cot∅=b/a

cosec∅=1/sin∅=√a²+b²/a

sec∅=1/cos∅=√a²+b²/b

Step-by-step explanation:
