week 15- converting equations from slope y-intercept form, y= mx + b to general form Ax + Bx + C= 0, where A, B, and C are integers

The general from of the equation of a line is an equation where all the terms are collected to the left side of the equation. The general form of an equation is written as Ax + By + C = 0, where A, B, and C are almost always expressed as integers, and A is usually positive.

This week I learned how to¬†convert equations from slope y-intercept form, y= mx + b to general form Ax + Bx + C= 0, where A, B, and C are integers. To convert equations from and to these forms I learned to take the following steps…

 

week 14- solving functions

In a function notation f(x) is read as “f of x” of “f at x”. f(x) does NOT mean f times x. f(x) provides a formula for the function f, and also represents the value of the function for a given value of x.

This week I learned how to solve functions. To solve functions I learned to do the following steps…

week 7- Solving for Right triangles

This week I learned how to solve for a right triangle. To do so I learned to do the following steps…

To solve for a right triangle, depending on the information given you can use the Pythagorean Theorem and/or trigonometry to solve the triangle.

When you have a right triangle (one angle is exactly 90 degrees) you can use trigonometry to solve the triangle using the sin cos or tan function. These functions also are known as soh, cah, toa.

Using the information given for the triangle above, we know that we have the hypotenuse and the opposite side measurements of the triangle. So we can use sin, because sin equals the opposite side length of the triangle over the hypotenuse side length of the triangle.

After solving the equation for this right triangle we would then type the equation into the calculator using the proper function to get the correct answer.
