trigonometry

:words:  sin :o/h.  Cos:a/h  tan:o/a

Opposite=O

adjacent=A

hhpotenuse=H

(Example)

sin 50°=0.766

Means that the opposite side is 76.6% of the

hypotenuseside.

cos12°=0.978

Means that the adjacent side is9.787 of the hypotenuse side

tan43°=0.932

Means that the opposite side is 93.3% of the adjust side

  1. Measurement

Cone               : SA=2πr ²+2πrh

⤵︎×2      :V=(area of base)×h

Sphere      : SA=4πr     ½ sphere : SA=½(4πr²)

: V=¾ πr³                     :V=½(¾πr³)


 

Reclangular Prism

SA=2(wh+lw+lh)

V=(area of base)×h

Week 4 Math

Rational Exponents    

example.

3√2.× 3√2 .3√2=3√8 →21/3  .21/3 .21/3=2

so.    x1/3=3√x1


Evaluate
