    integration

    what he meant was if you write csc x = sin-1x it can be mistaken as arcsin which is generally written as sin-1x i.e csc x = sin-1x can be mistaken to mean csc x = arcsin x

    Power, Current and Voltage

    V=I*R if R is constant, then, V is proportional to I if V increases then, because V and I are proportional, I will also rise

    proof for product rule(diff)

    \\$Define $f, g $ as functions of $x\\$Let $h=f\cdot g,\\\ln h=\ln (f\cdot g)=\ln f +\ln g\\$Differentiate with respect to $x,\\\frac{d}{dx}\ln h = \frac{d}{dx}\ln f + \frac{d}{dx} \ln g\\\frac{h'}{h}=\frac{f'}{f}+\frac{g'}{g}\\\Rightarrow h'=h \cdot\frac{f'\cdot g+f\cdot g'}{f\cdot g}=f'\cdot...

    a nice way using eulers: \\(1+\cos x+i\sin x)^n\\=(1+e^{ix})^n\\=\left(e^{i\frac{x}{2}}(e^{-i\frac{x}{2}}+e^{i\frac{x}{2}}) \right )^n\\=(2\cos \frac{x}{2})^n(\cos \frac{x}{2}+i\sin \frac{x}{2})^n\\=2^n\cos^n \frac{x}{2}(\cos \frac{nx}{2}+i \sin \frac{nx}{2})

    e^(i*theta)= cis(theta)

    nah its alright, covered left/right hand limits in my uni math course how is the derivative interpreted in the complex plane? e.g. it is the gradient function for real valued functions, how so for complex valued functions? (sorry about being annoying, ive read a few pdfs on complex analysis...
