## FAQ

Q: What are the basic trigonometric functions?
A: The basic trigonometric functions are sine (sin), cosine (cos), and tangent (tan).

Q: What is the Pythagorean identities?
A: The Pythagorean identities are formulas that relate the trigonometric functions of a right triangle. The identities include sin²θ + cos²θ = 1 and 1 + tan²θ = sec²θ.

Q: What is the formula for the sine function?
A: The formula for the sine function is sin(θ) = opposite/hypotenuse.

Q: What is the formula for the cosine function?
A: The formula for the cosine function is cos(θ) = adjacent/hypotenuse.

Q: What is the formula for the tangent function?
A: The formula for the tangent function is tan(θ) = opposite/adjacent.

Q: What are the reciprocal trigonometric functions?
A: The reciprocal trigonometric functions are cosecant (csc), secant (sec), and cotangent (cot) and they are the reciprocals of sine, cosine, and tangent respectively.

Q: What is the formula for the cosecant function?
A: The formula for the cosecant function is csc(θ) = 1/sin(θ).

Q: What is the formula for the secant function?
A: The formula for the secant function is sec(θ) = 1/cos(θ).

Q: What is the formula for the cotangent function?
A: The formula for the cotangent function is cot(θ) = 1/tan(θ).
