Trigonometry and Vectors

Applets (Internet Labs) -

Drawing Resultants

Boat on a River - demonstrates the actual application of adding vectors. The velocity vector of the river is added to the velocity vector of the boat.

Sin, Cos, and Tan (MC) - learn how to use them; you should do this exercise until it is very easy.

Trig Vocab (M)

Vector Basics (MC) - learn about direction, negative vectors and components.

Graphically Adding Vectors (MC) - learn to draw resultants.

Learning Vector Directions (MC) - an easy way to learn how to set up vector directions.

Vector Directions (MC) - same as above, but you have to figure out the angles.

Is Sin or Cosine Positive or Negative? (MC) - learn the implications for the directions above.

Finding Components (MC) - step by step

Finding Components 2 (MC) - step by step

Calculating Components (MC) - not step by step. Be sure you know how to do this before you attempt to add vectors.
