Question

I need four introduction sentences that talks about trigonometry and vectors for my physics lab. Please nothing from the internet, I need something original.

Answer 1

1. Vector is physical quantity contain magnitude as well as direction. i.e. Force, Velocity, Momentum

2. We can use trigonometry in vectors for simplification in form of its components i.e. X- component, Y - component and Z- Component. F_x= F cos θ

3. We can use trigonometry in product of vectors. Scaler product and Vector product

4. Trigonometry useful in projectile motion equations and also in conversion of polar coordinate into Cartesian coordinate.
