Sine Function: The sine function relates angles in a right triangle with their corresponding side lengths. It oscillates between -1 and 1 and has various applications in physics, engineering, and wave analysis.
Inverse Trigonometric Functions: These functions, including arctan, arcsin, and arccos, allow us to find angles given certain ratios or values from trigonometric functions.
Implicit Differentiation: Implicit differentiation is a technique used to find derivatives of equations that are not explicitly expressed in terms of one variable. It helps us differentiate equations involving multiple variables or functions.
