1. ### help with tan(u + v)?

...the trigonometric function given that sin(u) = -15/17 and cos(v) = -3/5. (Both u and v are in Quadrant...u = 15/8. You can do a similar thing to determine tan v knowing cos v, except that this time we know the length of...

2. ### In a triangle, the angles are u°, v° and w°.?

If v is half of w: v = w/2 and u is the mean of v and w: u = (v + w) / 2 And you know it's a triangle...w = 80 Now that we have w we can solve for v and u: v + w = 120 v + 80 = 120 v = 40 u = (v + w...

6. ### how do you solve for "v"?

- 5 - 4/(v - 7) = 7/([v + 1][v - 7]) - 5([v + 1][v - 7]) - 4(v + 1) = 7 - 5(v² - 7v + v - 7) - 4v - 4 = 7 - 5(v² - 6v - 7) - 4v = 11...

7. ### How do I prove: ∇ x (∇ x v) = ∇(∇ • v) - ∇²v?

Let v = (f, g, h). Computing determinants repeatedly yields ∇ x v = (h_y - g_z, f_z - h_x, g_x - f_y) ==> ∇ x (∇ x v) = ((g_xy - f_yy) - (f_zz - h_xz), -[(g_xx - f_xy) - (h_yz - g_zz)], (f_xz - h_xx...

10. ### Solve the equation: (v-5)^2 = 2v^2 - 3v + 37 for v?

(v-5)(v-5)=(v^2)-5v-5v+25=(2(v^2))-3v+37 subtract 25 from both sides yeilds v^2-10v+0=(2(v^2))-3v+12 add 3v to both sides yeilds v^2-7v+0=(2(v...
