Trigonometry is a topic that sends many pre-med students screaming for the hills, especially when it comes to applying sine, cosine, and tangent values to angles stated in an MCAT style question. The average student will memorize ‘radical 2 over 2' as the sin or cos value for a 45 degree angle, but how on earth do you incorporate that into an MCAT question without a calculator?

My newest video shows you my trick for recognizing when to use sin and cos, as well as my number pattern for sin/cos values to help avoid confusion in MCAT calculations.

I would for a continuation of the Forces videos, normal force, gravitational force, tension, friction, centripetal (especially), torque. Those are concepts I find difficult to grasp. I know with your videos it would make a lot more sense and I would be able to apply it.
