Find dy/dx 5x^2-y^2=2

Problem

5*x2−y2=2

Solution

  1. Differentiate both sides of the equation with respect to x treating y as a function of x

(d(5)*x2)/d(x)−d(y2)/d(x)=d(2)/d(x)

  1. Apply the power rule to the first term and the chain rule to the second term.

10*x−2*yd(y)/d(x)=0

  1. Isolate the term containing d(y)/d(x) by subtracting 10*x from both sides.

−2*yd(y)/d(x)=−10*x

  1. Solve for dy/dx by dividing both sides by −2*y

d(y)/d(x)=(−10*x)/(−2*y)

  1. Simplify the fraction by dividing the numerator and denominator by −2

d(y)/d(x)=(5*x)/y

Final Answer

d(y)/d(x)=(5*x)/y
