A function does not have an "angle of inclination"! I assume you mean "the angle of inclination with the x-axis of the tangent to the curve at any point".

If is the angle the tangent line to y= f(x) makes with x-axis than . - Sep 20th 2012, 04:59 PMpnfullerRe: Help angle of inclination
so what am i suppose to do with that? the answer is 63 degrees but how do i get that?

The slope of the tangent line is found by evaluating the derivative of the function at the given

*x*-coordinate.

The slope of a line is related to its angle of inclination by .

Hence, the angle of inclination is .
