I struggle with trigonometry and unit circles but my finance degree needs me to get to Calculus 2.

Is there any chance for me?

good luck

Yeah. memorize the common trigonometric values

>>

>>7642941

You can't memorize 5 points?

It can then be split into 4 quadrants that have the same value except changing signs with respect to quadrant.

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.

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.

Jesus Christ OP, gender studies has some spots open. Maybe you can be a barista one day.

Not if you remember what sin, cos, etc. actually represent.

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.

I can do the finance side of math, I just struggle with the abstract purely mathematical side.

>>7642983

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.

sheeeit

>>7643070

Go ahead and derive me the half angle formulas and double angle formulas in less than 3 steps from that

>>

>>7643070

this is just blatantly wrong. the periodicity of the trig functions are not even implied from that

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)⌋

Let ϕ=θ

I see you haven't taken calc 2

disk meth, shell meth, u sub, trig sub, parts, Taylor rights, ratio test, root test

simple shit
