Tag: Plane Trigonometry Solution

Solution: Simplify cos^4 θ – sin^4 θ 

Solution: Solve for x: x = 1 – (sin θ – cos θ)^2

Solution: Solve for x: x = (tan θ + cot θ)^2 sin^2 θ – tan^2 θ

Solution: Solve for y if y = (1/sin x – 1/tan x)(1 + cos x)

Solution: Solve for x from the given trigonometric equation

Solution: Solve for x in the equation: arctan (2x) + arctan (x) = π/4

Solution: arctan [2 cos (arcsin (√3/2))] is equal to

Solution: If cos Ѳ = x/2 then 1 – tan^2 Ѳ  is equal to

Solution: If x + y = 90°, then ((sin x tan y)/(sin y tan x))  is equal to

Solution: If sin x + 1/sin x = √2, then sin^2 x + 1/sin^2 x is equal to
