Most students think slope-intercept form is the bomb, but if you're in calculus, it's almost always way quicker to use point-slope form. Not sure what I'm talking about? That's why this video!

Finding Equation of Tangent Line

In this video we use our refreshed knowledge of point-slope form to find the equation of the tangent line of a function at a given point. Why are we doing this? Just one of the many skills calculus is known for! Also, since derivatives are all about the slope of the curve, you can use the equation of the tangent line to approximate stuff. Pretty awesome?
