to differentiate this equation we have to do it in two parts because there is a minus sign seperating them in the middle for the first part we first have to multiple the constant by what the power of x is wh...

First of all you need to separate the two numbers you have 8Y and 4y2 then ask yourself what you can divide both these 2 numbers with? so 4 can be divided by 4 and 8 can be divided by 4. so we can divide bot...

If you imagine that sin(x), cos(x), -sin(x) and -cos(x) are on a wheel as shown below: sin(x) -cos(x) cos(x) -sin(x) then going clockwise around the wheel you have what each term differentiates to, so sin(x)...

Firstly, we are given that f(x) can be expressed in the above form, so we write this out: (19x-2)/((5-x)(1+6x)=A/(5-x)+B/(1+6x) We then multiply by the denominator of f(x): 19x-2=A(1+6x)+B(5-x) Now we can ch...

While this question may appear unfamiliar at first, it is just a quadratic equation in disguise. Rearranging such that it equals 0: x^2 + 5x - 36 = 0 Now this equation is ready to be solved! We can approach ...
