Maximizing Slope: Solving for Tangent Line on y=1+40x^3-3x^5 Curve

In summary, the equation for the tangent line on the curve y=1+40x^3-3x^5 is y=120x^2-15x^4+1. The slope of the tangent line at a specific point (x, y) on the curve can be calculated using the power rule. To find the equation of the tangent line, you will need to determine the slope at a specific point and use the point-slope formula. The power rule can be used to find the slope of the tangent line on any curve in the form of y=x^n. Finding the tangent line on a curve is important for determining the instantaneous rate of change of the curve, which has many practical applications.
