Math (trigonometry)
Didn't you just factor that? (perfect square trinomial) I'm looking for a way to solve it without factoring..

Math (trigonometry)
How do you solve this trig identity problem without factoring? I just used @ to represent theta: sin^4@ + 2sin^2@cos^2@ + cos^4@ = 1

No, because 3x_ can NEVER equal to 16 so 16 divided by 3 has no answer. There will be one left out.

A 35 kg box rest in the bed of a truck. The coefficient of static friction between the box and the truck bed is 0.30 and the coefficient of friction of kinetic friction is 0.10. A) Calculate the maximum acceleration the truck can have before the box slides backwards. B) The tr...

How do you know how long you need to draw the vectors? Like if the gravity vector line is longer than the normal force, or if the friction line is longer than the applied force or whatever..?

A 59.0-kg skater is traveling due east at a speed of 1.80 m/s. A 61.0-kg skater is moving due south at a speed of 6.20 m/s. They collide and hold on to each other after the collision, managing to move off at an angle south of east, with a speed of vf. Find (a) the angle and (b...
