This week I learned how to use trig to solve problems that include bearings. Bearings: Each direction has a 3 bearing number that tells you the angle of direction they’re at North=000, east=090, south=180, west= 270, and everything in between… Continue Reading →

This week I learned how to use trigonometry to find angles and the length of sides. Every trig equation is: ratio(reference angel)=side 1/side 2 Ratio (cos, sin, tan) To find the length of sides using trig: First you have to… Continue Reading →

This week I learned how to do the surface area and volume of spheres/hemispheres. The diameter of a sphere = the height of the sphere Volume of a sphere= volume of 2 cones = 4/3 Surface area of a sphere… Continue Reading →

This week I learned how to convert imperial measurements to metric, and the other way around. At first I had some trouble with converting one unit to two, so cm into feet and inches, but I think now I understand. First… Continue Reading →
