math post – week 6

categories: Math 10

The variable in this equation is on the bottom of the cosine equation so that means we have to switch the two around and then put the variable on top of the cos number. Then divide as intended

This is also a cosine problem but this time all we have to do is put the x on the opposite side of the equation and then turn cos into an inverse cosine and do cosine 5/6

The variable is on the top for this one as well so all that has to happen is the inversion again as the problem anove

    Minor details but in the 1st one, it would be helpful if you showed both sides being “reciprocated” … when one is and the other one isn’t, could be confusing for anyone who is reading this.

    In the second one, the x is actually not moving, but rather the cosine is, to the other side of the equal sign and changing to cos^{-1}

    And in the final example, when the x is on the right, you are moving the 42.2 to the other side (no inversing here), just changing a number that was originally dividing to a multiply number on the other side.
