Integration helo

When I integrate this, I get two Cs?
Also,is there a efficient way of finding the coefficients rather than just getting as many equations as possible and doing simultaneous equations?

Since you already have C in your original equation to find the intercept part of the equation after integrating use a different letter like +d. As if there are 2 Cs it suggests that they have the same value when you don't know whether they do or not
Maybe write it as cic_i to show that it's the constant of integration?

The information about the gradient at (0,1) should immediately give you cc

You can then integrate and use the fact that the curve passes through (0,1) to find your constant of integration (call it d or whatever).

That leaves you with just a and b to find, and you can set up a pair of simultaneous equations to do that :smile:
