# Trigonometry

In this section I learned about trigonometry and this included SOH CAH TOA

SOH  CAH TOA helped me when it came to finding each side of a right triangle

for example if the triangle gives you the hypotenuse and opposite then u should use the sin this is why it is SOH

And you use cos when u have the Adjacent and  hypotenuse

# Measurements 2nd half

This week I learned the difference between the metric and imperial systems and how to convert them;

• the imperial system is the american system which includes miles, feet, inches, and yards
• The metric system which most of the world uses, includes kilometers, meters, and cm

I also learned how to find the surface area and volume of prisms and cylinders;

Volume of prism= the area of the base of prism x height

Surface area of prism= add the areas of all the surfaces together

area of base= 2(pi)r

# Exponents

During our unit on exponents i have learned how to simplify and solve equations that included exponents. This included when multiplying two or more numbers with the same base you can add the exponents.

For example:  $x^4$ +$x^4$ = $x^8$
