Question

Find the tangent line to 4x^2-3y^2=13 at the point (-2,1). Express your answer in the form y=mx+b.

Answer 1

Take the derivative, then substitute the point

Answer 2

first differentiate the function
this will give u slope of the tangent
then use general form of straight line substituting the given point

Answer 3

how can i differetitate i know how to take the derivate of 4x^2-3y^2 but i dont know how to solve it when it equals 13
