Note: for what’s about to come, ' denotes derivative with respect to x. Method 1 (integration by parts): let I = (e^x)sin(x) dx let u = sin(x)...
Assuming you know the equation of the line, this could possibly be done in several ways. If you are able to integrate the equation of the line definitely using your current knowledge, then do this between...
Differentiation is a very useful concept; informally it tells us how 'fast' something is changing. A real-life example is given by the first and second derivatives of distance with respect to time: the fi...
To calculate the minimum value of A we first need to establish an equation for A. The surface area of a cuboid is relatively simple to figure out we simply work out the area of the faces and sum them toge...
y=-4x-1 (-4x-1)^2 +5x^2 +2x=0
16x^2 +8x +1 +5x^2 +2x=0
21x^2 +10x + 1 =0 (7x+1)(3x+1)=0
x=-1/7 or -1/3
y= -3/7 or 1/3
