This is an example of implicit differentiation, where the function in question involves two variables (x and y) and it is hard to rearrange to create a neat "y=..." equation. To differentiate th...
So here we need to use the chain rule in order to differentiate the equation. To start you take the function inside the bracket x2+4x and differentiate it to Du/Dx= 2x + 4 this is known as u. d...
2sin^2(x) + 3sin(x) = 2cos(2x) + 32sin^2(x) + 3sin(x) = 2(cos^2(x) - sin^2(x) ) + 32sin^2(x) + 3sin(x) = 2(1- 2sin^2(x) ) + 32sin^2(x) + 3sin(x) = 2 - 4sin^2(x) + 36sin^2(x) + 3sin(x) - 5 = 0 let sin(x) =...
a) Sub x=3 into the given equation. N is found to be 25.b) Finding dy/dx gives me, as the first differential is the gradient.First differentiate the power and then multiply the differential of the express...
First we draw a diagram of this system (on whiteboard). Remember to label diagram correctly - the tension on both sides act towards each other. Since B is a larger mass, we know that mass A will mov...
