Answer:
We know
sin (A + B) = sin A cos B + cos A sin B
sin (A - B) = sin A cos B - cos A sin B
(A + B) + sin (A - B)
= sin A cos B + cos A sin B + sin A cos B - cos A sin B
= sin A cos B + sin A cos B
= 2 sin A cos B
A negative sign and a negative sign next to each other is a positive sign ex..
-14 - -3
= -14 + 3
= -11
a negative sign and a positive sign next to each other is a positive sign ex..
-14 + -3
= -14 - 3
= -17
the bigger a negative number the smaller it is
the bigger a positive number the larger it is
which supports the rule if you are subtracting the
number will become smaller and if you are adding
the number will become larger
Simplify terms, then move the terms over so 'y' is by itself.
-7y-0.6=3.6-y
-0.6-3.6=-y+7y
-4.2=6y
y=-4.2/6
y= -0.7
Step-by-step explanation:
When you raise a number to the power with the exponent 1/2, you get a square root of a number.
Generally:
![a^\frac{1}{n}=\sqrt[n]{a}](https://tex.z-dn.net/?f=a%5E%5Cfrac%7B1%7D%7Bn%7D%3D%5Csqrt%5Bn%5D%7Ba%7D)
for n - whole number, n ≥ 2.
