Question

What is the value of $\sin 90^\circ + \cos 0^\circ$?

Hint:

Important values to memorize: \[ \sin 0^\circ = 0, \quad \sin 90^\circ = 1 \] \[ \cos 0^\circ = 1, \quad \cos 90^\circ = 0 \] These are frequently used in basic trigonometry.

Answer 1

Concept: Standard trigonometric values: \[ \sin 90^\circ = 1, \quad \cos 0^\circ = 1 \] Step 1: Substitute known values \[ \sin 90^\circ + \cos 0^\circ = 1 + 1 \] Step 2: Simplify \[ = 2 \] Final Answer: \[ \boxed{2} \]
