Find the integrals. (show steps) (integral sign) xe^(4x^2) I think this how is how its done: (integral sign) xe^(4x^2) it's a u du problem let u=4x^2 so, du=8x dx now you have an x already so all u need is 8 inside and and 1/8 outside the integral [1/8] (integral sign) [8]...

find the integral secxtanxdx and if dy/dx= 2x/y^2 and y(o) = 3 then what is y(1) equal to and differentiate 2pi + 3secx secxtanxdx = Sin(x)/Cos^2(x)dx The integral is 1/Cos(x) + c dy/dx= 2x/y^2 and y(o) = 3 then what is y(1) equal to y^2 dy = 2x dx ---> 1/3 y^3 = x^2 + c y(...

math
What is the equation of the tangent line given the curve: y = (3+lnx)^2 at x = 1/e dy/dx = 2[3 + Ln(x))]*1/x at x = 1/e this is: 4*e y(1/e) = 4 The equation of the tangent line is thus given by: 4e(x-1/e) + 4
