Prove the identity
csc x cot x cos x = sin x
Proof:
L.H.S.
csc x cot x cos x = 1 sin x cos x sin x cos x = 1 cos 2 x sin x = sin 2 x sin x = sin x       R . H . S

I'm in highschool and just started integration. I found the following problem in an old question paper and I find it very challenging.
0 1 x 2 2 x + 1 d x
so I simplified it algebraically to
0 1 ( x 1 ) 2 d x
which of course is
0 1 | x 1 | d x
as the absolute value is a linear function over x [ 0 , ) so I proceed to evaluate it as x 2 / 2 x for upper limit 1 and lower limit 0 which is ( ( 1 ) 2 / 2 1 ) ( 0 0 ) and equals 1 2 , but according to wolfram alpha it is 1 2 .
Please explain at beginner level.

The determined Wile E. Coyote is out once more to try to capture the elusive roadrunner. The coyote wears a new pair of power roller skates, which provide a constant horizontal acceleration of 15 m/s2, as shown in Figure P3.73. The coyote starts off at rest 70 m from the edge of a cliff at the instant the roadrunner zips by in the direction of the cliff. (a) If the roadrunner moves with constant speed, find the minimum speed the roadrunner must have to reach the cliff before the coyote. (b) If the cliff is 100 m above the base of a canyon, find where the coyote lands in the canyon. (Assume his skates are still in operation when he is in “flight” and that his horizontal component of acceleration remains constant at 15 m/s2.)
