Need to get the point in a (curved) line which has the same tangent as another (straight) line

Hello everyone,

I have quite an interesting problem: I am trying to create a line which i already know the tangent of, but i do not know where that exact tangent is on my curved line. See my illustration below:

Thanks in advance!

Finding the Min/Max of Polynomials

I’m trying to code a quadratic equation with the ability to find the min and max at the same time within a given range. Later these points can be used to start adding structure too but I’m having trouble getting the code started. Eventually I’d like to find min/max of a series of sin waves but will start will quadratic equations first. Thanks, def quadmin(a, b, c, xmin, xmax); q0 = (a * xmin + b) * xmin + c; q2 = (a * xmin + b) * xmax + c; x1 = -b/(2*a); if (xmin < x1 ) …
