When integrating we add one to the power of x and divide the number in front of the x by the new power for each part of the function. So 2x^2 becomes 2/3 x^3, 4x becomes 4/2 x^2, 1 becomes 1/1 x^1. Then w...
d(sin3y)/dx= 3cos3y*(dy/dx)d(3ye^(-2x))/dx = -6ye^(-2x) + 3(dy/dx)e^(-2x)d(2x^2)/dx = 4xd(5)/dx = 0so3cos3y(dy/dx) - 6y*e^(-2x) + 3(dy/dx)e^(-2x) + 4x = 0rearrange the equationdy/dx ...
ln(a^x) = ln(b^y) = ln((ab)^(xy))xln(a) = xyln(ab)ln(a) = yln(ab) = y(ln(a) + ln(b))y = ln(a)/(ln(a)+ln(b))with same analysis for ln(b^y):ln(b) = x(ln(a) + ln(b))x = ln(b)/(l...

To find the gradient of a function, that has constant gradient you pick any two points. You label both the x and y co-ordinates of these two points.Then you subtract the y co-ordinates of these two points...
