Precalculus SOH CAH
how are the following relations true? S(theta + pi/2) = C(theta) and C(theta + pi/2) = -S(theta)?

math
You do 14500 times .09 then you add that to 14500 to get year 1 then repeat that till you get 22309.51.or something close to that.

Derivatives (check answer)
Let y=x^5 - pi^5. Find dy/dx My answer is 5x^4 because pi^5 becomes 0? Am I correct?

Algebra (Please check)
Number 1 I know is D

PLEASE CHECK MY ANSWERS (: I just want to make sure I am doing this correctly __________________________________ Graph the system of constraints and find the value of x and y that maximize the objective function. Constraints: x ≥ 0 y ≥ 0 y ≤ (1)/(5) x + 2 5 &...

Algebra (Need help desperately)
Thanks :D I'm 90% sure number 1 is D, but do a good way how I could do 2 or 3? If you dont mind explaining to me?

Precalculus
he distance between 2 points (x1,Y1) and (x2,y2) is given by d = square root (x1-x2)^2 + (y1-y2)^2 a - pick 2 arbitrary points in 3 dimensions, (x1, y1, and Z1) and (x2,y2,z2) and plot these points. Not that there are 90 degrees between the xy, xz, and yz axes. b- using your s...

Calculus (Check)
This seems to easy. Check please. Find. Lim (x^2)-4 x->2 e I substitute in 2 (2^2)-4 e gives me 4-4 e So my answer is e^0 or 1.

Calculus with Analytical geometry
I'm stumped on this one. lim |x-1|sin(1/x-1) x->1
