Answer

Step3: Now that we have the slope of the tangent line and the point (1,0), we can use the point-slope form of a line to find the equation of the tangent line. The point-slope form of a line is yy1=m(xx1), where (x1,y1) is a point on the line and m is the slope of the line. Plugging in the values we have, we get y0=3(x1). Simplifying this gives us the equation of the tangent line: y=3x+3.

Steps

Step 1 :Step1: First, we find the derivative of y=x33x2+2. The derivative of the function, denoted as y or f(x), gives us the slope of the tangent line to the curve at any point x. Using the power rule for differentiation, we get y=3x26x.

Step 2 :Step2: Then, we plug x=1 into y to find the slope of the tangent line at the point (1,0). We get y(1)=31261=3. So, the slope of the tangent line is -3.

Step 3 :Step3: Now that we have the slope of the tangent line and the point (1,0), we can use the point-slope form of a line to find the equation of the tangent line. The point-slope form of a line is yy1=m(xx1), where (x1,y1) is a point on the line and m is the slope of the line. Plugging in the values we have, we get y0=3(x1). Simplifying this gives us the equation of the tangent line: y=3x+3.
