Step-by-step explanation:
In a right triangle, the cosine is the ratio of the adjacent side to the hypotenuse:
The adjacent side is the side that makes up the angle but is not the hypotenuse.
I'm assuming the answer box should ask for cos(theta) rather than cos(x).
Answer:
Logo, no intervalo [0°,360°] as soluções da equação sen2x=–senx . São: . 0°,120° ... k∈Z . S={x∈IR: X=(π\2)+2kπ , k∈Z } . b) arccos(2x²–1)=2arccos(1/2) .
Step-by-step explanation:
i know it
When rounding off the rule is you round off to the nearest 5.
17.2 would then be rounded of to 17. should it have been 17.5 you would then round up to the next 5 which would be 18
To find the 50th term in this sequence, first you need to find how what the sequence is. To get from 5 to -2 you're subtracting 7, to get from -2 to -9, you subtract another 7. In order to get the next number you go down by multiples of 7: 5 - 7 = -2; 5 - 14 = -9 and so on). So all you have to do is multiply 7 by 50 to get 350 and subtract that from 5 to get -345.
