The basic trigonometric ratios are sine, cosine, and tangent. These ratios are used to relate the sides of a right triangle to its angles.
The Pythagorean theorem in trigonometry states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
The unit circle in trigonometry is a circle with a radius of 1 unit, centered at the origin on a Cartesian plane. It is used to understand the values of trigonometric functions for any angle.
Sine and cosine are both trigonometric ratios, but they differ in the sides of a right triangle that they relate to an angle. Sine relates the opposite side to the hypotenuse, while cosine relates the adjacent side to the hypotenuse.
To solve for an unknown side or angle in a right triangle, you can use the trigonometric ratios and the given information about the triangle. For example, to find the length of the side opposite to a given angle, you can use the sine ratio: sin(angle) = opposite/hypotenuse. Rearranging the equation, you can solve for the unknown side.
