Step-by-step explanation:
LHS= sin 3x/sin x - cos 3x/cosx
Taking LCM,
<u>=</u><u>sin3xcosx- cos3xsinx</u>
sinxcosx
<u>=</u><u>sin(3x-x)</u>
sinxcosx
= <u>2sin2x</u>
2sinxcosx
=<u> </u><u>2sin2x</u><u> </u>
sin2x
=2
= RHS.
Proved.
The answer is B because the slope 4/1 fits the graph
Answer:
2
Step-by-step explanation:
greatest common factor means the greatest number we can divide by for each of the number and still get a whole number
14 and 22. they are both even so one factor is 2
if we check, 14 & 22 aren't both divisible by 3,4,5,6,7,8,9,10,11,12,13,14 so the gcf is 2
Answer:
.00354
Step-by-step explanation:
