Web\tan (x) = \dfrac {1} {\cot (x)} = \dfrac {\sin (x)} {\cos (x)} tan(x) = cot(x)1 = cos(x)sin(x) Notice how a "co- (something)" trig ratio is always the reciprocal of some "non-co" ratio. … WebFrom the form a^2 - x^2 he said x could be written as x=asin (theta) Then you got that 8 - 2x^2 could be rewritten as 2 (2^2 - x^2). There you have your "a" on the thing you got now inside the parenthesis, and it is equal to 2. So if you replace it on what you had as x=asin (theta) you get x=2sin (theta) ( 17 votes) Upvote Flag Show more...
