Exercise · ZW-DERIVATIVES-OF-TRIG-FUNCTIONS-006 · ★☆☆ Basic
Differentiate \(f(x)=\sin {x}\).
Choose one option.
Show answer
- A. \(\cos {x}\)
Explanation
By the basic derivative of sine (in radians): \((\sin {x})'=\cos {x}\).
Review the concept: Derivatives of trigonometric functions
These are the derivatives of sine, cosine and tangent, with angles in radians; the others follow from the quotient and chain rules.
\[(\sin x)'=\cos x,\quad(\cos x)'=-\sin x,\quad(\tan x)'=\sec^{2}x\]
