Class 11 Physics (India): Worked example: Derivatives of sin(x) and cos(x)

Sal differentiates g(x)=7sin(x)-3cos(x)-(π/∛x)². This can be done using the derivatives of sine and cosine, and the Power rule.

Class 11 Physics (India)

Let's learn, practice, and master topics of class 11 physics (NCERT) starting with kinematics and then moving to dynamics with Newton's laws of motion, work, energy, and power. Let's then use these as the foundation to learn about centre of mass, rotational motion, gravitation, solids, fluids, thermodynamics, and oscillations and waves.

Sine & cosine derivatives

The derivative of sin(x) is cos(x) and the derivative of cos(x) is -sin(x). How convenient! Practice differentiating functions that include sine and cosine.
