Thanks in advance. Last edited by skipjack; June 1st, 2019 at 02:09 PM.

You might be better off studying from a text. Thanks from topsquark

Using function $\displaystyle f(x)=ax+b$ Slope is $\displaystyle \tan \beta = \frac{y_1 - y_2}{x_1 - x_2}$ $\displaystyle f'(x)=x$ $\displaystyle \int_a^b f(x) = ax^2 + bx + c$ If you can solve the problem of the area between 3 intersecting lines, you're probably good to go.
