..Find eguation of tangent to each curve at a given point:
2x^2y^3 + 3xy+5=0 (1,-1)
The only thing that throws me off is two variables
Mr F says: Use implicit differentiation to get dy/dx. Then proceed in the usual way.
y=2sin(x) + cos^2x (pi/6, 7/4)
I am pretty sure I know how to do this, just want to double check. Mr F says: If you want your work double checked, please post that work (all of it, not just your answer).
Thx in advance
