Using the identity:
, we get:
There are two solutions to this equation:
1) Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2) Therefore, there are 3 solutions to the given trigonometric equation.
Answer:
the one elephant that felt threatened the herd had gotten a little ways in front of him there for when he started running 10 miles per hour instead of the six that the other elephants were walking he caught up by doing four miles per hour more then the other elephants were going at the time
Answer:
I'm not quite sure what you are asking but I think the pattern would lead to -3 being your answer.
Answer:
Solution set = {25}
Step-by-step explanation:
=>
Dividing both sides by -1
=>
Taking square on both sides
=> x = 25
<em><u>Solution set = {25}</u></em>
