Derivatives of Inverse Trigonometric Functions: Derivatives Of Inverse Trig Functions Worksheet
Inverse trigonometric functions, also known as arcus functions, are the inverse functions of the trigonometric functions. They play a crucial role in calculus, allowing us to find the derivatives of composite functions involving trigonometric functions.
Derivative Formulas
- arcsin(x) = 1/√(1-x²)
- arccos(x) = -1/√(1-x²)
- arctan(x) = 1/(1+x²)
- arccot(x) = -1/(1+x²)
- arcsec(x) = 1/|x|√(x²-1)
- arccsc(x) = -1/|x|√(x²-1)
These formulas are derived using the chain rule, which states that the derivative of a composite function is equal to the product of the derivatives of its constituent functions.
Applications in Calculus
Inverse trigonometric derivatives are used to find the derivatives of composite functions involving inverse trigonometric functions. For example, the derivative of y = arcsin(x²) is given by y’ = 2x/√(1-x⁴).
Inverse trigonometric derivatives have applications in various fields, including physics and engineering. For instance, they are used to analyze the motion of objects moving in circular or oscillatory motion.
