Ok I know that the slope of a straight line is the same thing as x with a dot aboce it or simply the first derivative of x

on the unit circle tangent gives you the slope of the reference line right? This can be expressed using the notation expressed above but how?

Thanks!

  • PreCalculus -

    x with a dot above it usually represents the derivative with respect to time.

    I don't know what you mean by "the reference line" or "the notation expressed above". I also don't see what unit circle is involved.

    How do you find Altitude and slope slope is the derivative of a function: for ex. if you have f(x)=x^2 + x, at point (1,2) f'(x)=2x+1 your slope is 2(1) + 1 = 3 =m to find the equation is y-y1=m(x-x1) so you have: y-2=3(x-1) gives …
