This week in math I have learned how to simplify polynomial equations.
How to solve for sin, cos and tan on a right triangle:
SOHCAHTOA is helpful to memorise the equations for sin, cos and tan.
SOH is sin= opposite/hypotenuse
CAH is cos= adjasent/hypotenuse
TOA is tan= opposite/adjasent
the hypotenuse is found diagonal from the 90 degrees point, the adjacent side is found next to the angle point, and the opposite side is found across from the angle.
here are some examples of how to solve missing parts of a triangle:
This week in math I have learned how to convert different measurements in the Imperial System: Example: 0.04mm to meters.
using this scale, every line up you divide by 10 and every line down you multiply by 10.
So on the scale you go up 3 steps, from mm to meters, dividing by 10 each step. so in total. so you would divide 0.04 by 1000, which would equal 0.00004, or 4 x 10 to the -5
