The formula for solving a trigonometry problem involving sin θ / √1-sin^2 θ is: sin θ / √1-sin^2 θ = sin θ / cos θ = tan θ
The Pythagorean identity states that for any angle θ, sin^2 θ + cos^2 θ = 1. This identity is used in solving trigonometry problems by manipulating equations to get them into a form where the Pythagorean identity can be applied, simplifying the problem.
To find the values of θ that make sin θ / √1-sin^2 θ undefined, set the denominator equal to 0 and solve for θ. In this case, √1-sin^2 θ = 0, so sin^2 θ = 1. This means that θ = 0 or π (plus or minus any integer multiple of π).
The unit circle is a circle with a radius of 1, centered at the origin of a coordinate plane. It is used in solving trigonometry problems as a reference for the values of trigonometric functions for any angle θ. By using the unit circle, we can easily find the values of sin θ and cos θ for any angle.
You can check your answer to a trigonometry problem involving sin θ / √1-sin^2 θ by using a calculator to calculate the value of the expression for the given angle θ. You can also verify your answer by using the Pythagorean identity and checking if the equation is satisfied.
