To get the inverse "relation" of an expression, we first off, do a quick switcharoo of the variables, and then solve for "y", so let's proceed,
and yes, the domain for the range 0 ⩽ x
<span>⩽ 2, let's get instead the "range" of the original function,
</span>
<span>
</span>
Find the factors and get the ones common to both of them
45=3 times 3 times 5
81=3 times 3 times 3 times 3
so the factors common to both are 3 times 3 which is 9
1. All negative numbers added together are still negative
2. There is a proof and a theorem for it.
3. If it is an animal, then it has fur
Write out the sum formula for sin
<span>sin(x + y) = sinxcos + sinycosx </span>
<span>Then expand sin(a + b) + sin(a - b) </span>
<span>sinacosb + sinbcosa + sinacosb - sinbcosa </span>
<span>The 2nd and 4th terms cancel and you get </span>
<span>2sinacosb</span>
