>>7642950 It's honestly my first time seeing them all and it's at a point where all of my social classes are extremely crammed with tests and papers so I'm just a bit overwhelmed. I'm doing well in the class but the word problems and all are confusing me but I think I'm getting better.
>>7642945 calculus is actually easier. trig is a shitload of random incoherent rules and methods, calc is just chain rule, product rule and quotient rule. OP may struggle on integration but at least he will get 50% on differentiation alone.
>>7642970 That's the thing, I've done a a good bit of derivatives and such and I'm fine. I'm really actually fine with the trig functions. My problem comes in during applicators of radians and circles. It just kind of goes past me.
>>7642972 I can do the finance side of math, I just struggle with the abstract purely mathematical side.
Finance is just about the only non-stem field with the same starting as some stem and a non-capped salary possibility. My minor is Chem and I'm getting an MBA so my hope is to get into the corporate areas of a stem field with investments, actuarial science, and banking to fall on.
Calculus 2 requires you to do trigonometric substitution and finding solutions to trig integrals with trig functions raised to powers greater than 1. These sound hard but really aren't. You don't have to be a trig superstar, but you should know your unit circle and your trig identities.
Let the unit vector on the x axis be ⌈1⌉ ⌊0⌋ and the unit basis vector in the y direction be ⌈0⌉ ⌊1⌋ Then the matrix A(ϕ) that rotates (counter clockwise) a vector by ϕ will take the unit vector in x direction to ⌈cos(ϕ)⌉ ⌊sin (ϕ)⌋ and takes the y vector to ⌈-sin(ϕ)⌉ ⌊cos(ϕ)⌋ From this A(ϕ) equals ⌈cos(ϕ) -sin(ϕ)⌉ ⌊sin (ϕ) cos(ϕ)⌋ Thus the unit vector at θ to the x axis will be rotated to θ+ϕ after applying A(ϕ) ⌈cos(ϕ+θ)⌉=⌈cos(ϕ) -sin(ϕ)⌉*⌈cos(θ)⌉ ⌊sin (ϕ+θ)⌋=⌊sin (ϕ) cos(ϕ)⌋*⌊sin (θ)⌋
>>7642941 >>7643081 It might be a little overkill, but if you learn based Euler's relation now, you actually can derive the trig relations in just a handful of steps, on the fly. No memorization required.
