1. ### Determine the angle measure between vectors u and v?

u = 4i - 2j tan(u) = - 2/4 = - 1/2 → angle_u = - 26.565° v = i + 3j tan(v) = 3/1 = 3 → angle_v = 71.565° angle between u and v: = 71.565 - (- 26.565) = 71.565 + 26.565 = 98.130°

2. ### How do I solve for u?

Given: (5u+3/4) = (u-4/5) +11 ()s are not needed so we remove them: 5u + 3/4...4/5 + 11 - 3/4 Create a common denominator on the right hand side: 5u - u = - 16/20 + 220/20 - 15/20 Combine like terms: 4u = 189/20 ...

5. ### can you explain my mistake on u= tan(x/2) on how to proof sin(x)= 2u/1+u^2?

u = tan(x/2) 1/u = cot(x/2) (1/u)^2 = cot(x/2)^2 (1/u)^2 = csc(x/2)^2 - 1 1 + (1/u)^2 = csc(x/2)^2 (1 + u^2) / u^2 = csc(x/2)^2 u^2 / (1 + u^2) = sin(x/2)^2 u^2 / (1 + u^2...

6. ### Write the trigonometric expression as an algebraic expression containing u and v. cos(tan^-1 u + tan^-1 v)?

cos(arctan(u) + arctan(v)) => cos(arctan(u))cos(arctan(v)) - sin(arctan(u))sin(arctan(v)) cos(arctan(u)) => 1/sec(arctan(u)) => 1/sqrt(1 + tan(arctan...u^2)) * (v/sqrt(1 + v^2)) => (1 - uv) / sqrt((1 + u^2) * (1 + v^2))

8. ### math problem: solve for u?

Express 1 as a fraction: ( -2/(5u+10) ) - (5u+10)/(5u+10) = 2/ (u+2) Subtract fractions on left side: (-2-5u-10)/(5u+10... of the original equation. So the only answer is u = -4.4.

10. ### Math: Integrate using u-sub?

u = x-8 --->int of (u+8)u^(1/2) du = (2/5)u^(5/2) + (16/3)U^(3/2), then substitute x back
