Guessing the first two term is straight forward, but they won't work for 53. So I wanted to add another term to fix it for 53 by adding a third term. But the third term that I must add should evaluate to zero for x=5 and 8. I was able to think only floor function for that job.

rem(x,4) is the reminder function. 'floor' is the largest integer less than the value of the argument.

4x + rem(x,4) - 2 floor(x/10), where x=5 or 8 or 53

but I just found out I could just use the GC for that particular mod since it’s not main focus

The most general way is the Gauss-Jordan method, but it is slow

You know hyperbolic functions ? I use hyperbolic substitution for the integral on LHS

Gradient of AM X gradient of BC = -1
Because AM and BC are perpendicular to each other.

This one means, theres a line BC
Let the midpoint of BC be M

just wanna find out from anyone if there’s a one size fits all method of finding matrix inverse.

seems like there’s diff method for finding 2x2, 3x3 and so on type of matrices

alternatively, go straight to TYS, but there will be a bit of standard jump if student's foundation is not strong

After further simplification u can get y as just quadratic function of x
