I have a calc test coming up and I need help in the following areas. If you can help it would be great.
I need help with implicit differentiation. For instance differentiaite xy+8x=10-2y. I'm really stuck in this area. Obviously differentiating 8x is 8, 10 is 0 and -2y is -2 but the xy part has me confused.
How do I simplify (1+3i)(3+2i). I thought you just times it out but that's not the answer.
Also using the Newton Raphson process to determine a value of x for which f(x)=0 using x1=1 and giving answer to five decimal places. f(x)=x^2+7x-3
Finally differentiating cos^(0.5)x, sqrt (sin x), f(x)=x cos x, f(x)=x^2 cos x and f(x)=(sin x)/x.
I understand that's quite a bit but they are the areas I'm struggling in.
