The formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of which function(s)? tangent only cosine only sine and tangent cosine and sine

cosine and sine

Explanation:

The motion of a projectile launched with initial velocity at an angle above the horizontal consists of two independent motions:

- on the horizontal axis, it is a uniform motion, with constant speed , so the horizontal position at time t is given by

- on the vertical axis, it is an accelerated motion, with constant acceleration downward and initial speed , so the vertical position at time t is given by

Therefore, we see that both cosine and sine are involved.
