1. The problem statement, all variables and given/known data Find an equation of the tangent line to the curve at the given point. 2. Relevant equations y=x¼ Point = (1,1) 3. The attempt at a solution Derivative of y is y' = ¼x-¾ Plugging in the derivative to the equation for a line: y-1=¼(x-1)-¾. My book's answer is Y=¼x+¾, but I don't know how they got there. Expanding ¼(x-1)-¾ gives me a nasty fraction with a radical that doesn't seem to come out to equal ¼x+¾. I'm not sure what to do next here.
