The SLOPE for x=1.07 is 2.5047 (shown in lower part of display, and also true when calculated from the derivative 3*X^2+X2 with X=1.07), but to draw the tangent, in the symbolic view you just have to write for F2 : SLOPE(F1,1.07)*(X1.07)+F1(1.07) I don't understand your reflexion about the derivative, as a tangent is always a straight line, whatever the function is.
