Answer

Answer:

D. cosine and sine

Explanation:

Step1: Analyze horizontal motion

The horizontal - component of the initial velocity of a projectile launched at an angle $\theta$ with initial velocity $v_0$ is $v_{0x}=v_0\cos\theta$.

Step2: Analyze vertical motion

The vertical - component of the initial velocity is $v_{0y}=v_0\sin\theta$. So, cosine and sine functions are used to analyze the horizontal and vertical motion of projectiles launched at an angle.
