Question

equations of trignometry​

Answer 1

Answer:

Basic Formulas

sin θ = Opposite Side/Hypotenuse.

cos θ = Adjacent Side/Hypotenuse.

tan θ = Opposite Side/Adjacent Side.

sec θ = Hypotenuse/Adjacent Side.

cosec θ = Hypotenuse/Opposite Side.

cot θ = Adjacent Side/Opposite Side.

hope this helps please mark me as brainlist please

Answer 2

Solution: We know that sin θ = 1/2 = sin π/6. Illustration: Solve the equation sin 6x + sin 4x = 0.

Trigonometric Equations with their general Solutions:

Trigonometrical equation General Solution

sin θ = 0 Then θ = nπ

cos θ = 0 θ = (nπ + π/2)

tan θ = 0 θ = nπ

sin θ = 1 θ = (2nπ + π/2) = (4n+1)π/
