`tan θ =-4/3` , ` sin θ` is

tan θ.sin^2 θ=

If sec θ + tan θ = 7, then evaluate sec θ – tan θ

Prove that the general solution of sin θ= sin α, is given by : theta=npi+(-1)^nalpha,n in Zdot

Prove the identity (sin θ + cos θ)(tan θ + cot θ) = sec θ + cosec θ

sin − 1 ( sin θ ) > π 2 − sin − 1 ( sin θ ) find the range of θ

sqrt((1+sinθ)/(1−sinθ) is equal to (a)secθ+tanθ (b) secθ−tanθ (c) sec 2 θ+ tan 2 θ (d) sec 2 θ− tan 2 θ

If cosα+cosβ= 3/2 ​ and sinα+sinβ= 1/2 ​ and θ is the arithmetic mean of α and β, then sin2θ+cos2θ is equal to

If cosα+cosβ= 3/2 ​ and sinα+sinβ= 1/2 ​ and θ is the arithmetic mean of α and β, then sin2θ+cos2θ is equal to

cosα+cosβ= 3/2 ​ and sinα+sinβ= 1/2 ​ and θ is the arithmetic mean of α and β, then sin2θ+cos2θ is equal to Yes No

For an acute angle θ, sinθ+cosθ takes the greatest value when θ is
