Tangent Equation
1. The problem is to find the equation of the tangent line to the curve given by \(y = x^5 - x^3 + 2\) at the point where \(x = 1\).
2. First, find the derivative \(\frac{dy}{dx}\), which gives the slope of the tangent line at any point \(x\).
$$\frac{dy}{dx} = 5x^4 - 3x^2$$
3. Calculate the slope at \(x=1\):
$$m = 5(1)^4 - 3(1)^2 = 5 - 3 = 2$$
4. Find the y-coordinate of the point on the curve at \(x=1\):
$$y = (1)^5 - (1)^3 + 2 = 1 - 1 + 2 = 2$$
5. Use the point-slope form of a line equation \(y - y_1 = m(x - x_1)\) with \(m = 2\) and point \((1, 2)\):
$$y - 2 = 2(x - 1)$$
6. Simplify the equation:
$$y = 2x - 2 + 2 = 2x$$
So, the equation of the tangent line is \(y = 2x\).
