3. ### 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°

4. ### 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 ...

7. ### 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...

8. ### 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))

10. ### 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.
