Explain why you cannot use the Distributive Property to evaluate an expression in the form of sin(a + b). Please illustrate with an example along with your explanation.

The distributive property is to multiply the outside of a parenthesis by each term inside, for example:

this cannot be done with the trigonometric functions such as the sine.

An example of this:

let's prove that we don't get the correct result using the distributive property in the following expression:

≠

We add the elements in the parentheses on the left side:

 ≠

this are known values of the sine function:

substituting these values we will get that:

-1  ≠ 0 +1

-1  ≠ 1

Thus we notice that we don't get the correct result using the distributive property.

The correct way to express the angle sum in the sine function is:

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
