Question

8.If is an acute angle and sinθ=cosθ , find the value of 2θ+θ-1

Answer 1

Answer:

80019

Step-by-step explanation:

Answer 2

Answer:

((3π/4)-1)

Step-by-step explanation:

(A is taken as theta)

sinA=cosA

sinA/cosA = 1

tanA=1

as A is accute angle so

A= π/4

so,

2*π/4+π/4-1

((3π/4)-1)
