Question

Why is the derivative of theta 1 and not 0. Isn't theta a number?

Answer 1

theta might be a variable

Answer 2

Why is theta a variable? Wouldn't tan theta --> theta be a number in radians?

Answer 3

if \(\theta \) is a number/constant,

\(\large \frac{d}{dx}(\theta) = 0\)

Answer 4

if \(\theta\) is a variable,

\(\large \frac{d}{d\theta}(\theta) = 1\)

Answer 5

So is theta a variable or number/constant?

Answer 6

Theta is just like x. Is x a number? You decide.

Answer 7

theta usually represents an angle,
if you are taking the derivative of the tangent of theta , you are trying to find the slope of that line for all possible angles theta

Answer 8

x is a number. y is a number. But they're variables, not constants.

Answer 9

What is NDER to support computations of derivatives?
