HELP ME, PLEASE. I REALLY NEED IT Find x:

cotx - cot2ⁿx

Step-by-step explanation:

Note: finding the sum not x

First rewrite the first term as:

1/sin2x = sinx / (sinxsin2x)  = sin(2x-x) / (sinxsin2x)  =(sin2xcosx - cosxsinx) / (sinxsin2x) = (sin2xcosx)/(sinxsin2x) - (cos2xsinx)/(sinxsin2x) = cosx/sinx - cos2x/sin2x = cotx - cot2x

Now the sum is:

S = cotx - cot2x + cot2x - cot4x +... + cot2ⁿ⁻²x - cot2ⁿx =cotx - cot2ⁿx

hope it will guide you

Step-by-step explanation:

53 centimetres or 0.53 metres

Step-by-step explanation:

1 metre = 100 centimetres

2 metres = 200 centimetres

So far, he has parked 147 centimetres away from the fire hydrant, whereas he needs to be parked 200 centimetres away.

Subtract 147 from 200 to get the remaining distance he needs to park further (in centimetres).

200 - 147 = 53

To convert your answer to metres, just divide your answer by 100 by moving the decimal two places to the left.

53 ÷ 100 = 0.53

I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!
