Find the equation of the tangent line to the curve y=5xcosx at the point (pi,–5pi). The equation of this tangent line can be written in the form y=mx+b where m= and b=

Find the equation of the tangent line to the curve y=6tanx at the point (pi/4,6). The equation of this tangent line can be written in the form y=mx+b where m is: and where b is:

4.2 18. show that the equation 2x-1-sinx=0 has exactly one real root.

show that the equation 2x-1-sinx=0 has exactly one real root. sin x = 2x-1 2x = sin x - 1 range of sin x is -1 to + 1 but how do you know that 2x is between -2 and 0 and so x is between -1 and 0

A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola y=2–x2. What are the dimensions of such a rectangle with the greatest possible area? I got Width = 4/1.732 but i don't know why its wrong I got Height = 4/3 which i...

nvm i got the answer

I put -1.454 for x2 but when I put -2.299 for x3 I got it wrong

i got it wrong
