Nettet17. mar. 2015 · ∫ 1 − x 2 d x = 1 2 x 1 − x 2 + 1 2 sin − 1 x + C For completeness and comparison, I'll add the conventional solution using x = sin t substitution. Here d x = cos t d t, so ∫ 1 − x 2 d x = ∫ cos 2 t d t = ∫ ( 1 2 + cos 2 t 2) d t = t 2 + sin 2 t 4 + C To return to x, note that t = sin − 1 x and sin 2 t = 2 sin t cos t = 2 x 1 − x 2. Share Cite

Nettet10. feb. 2015 · But since micro-controllers do not provide much computational freedom, I was looking to solve it as the integral of 1/ (1+x^2). Other than the fact that, integral of 1/ (1+x^2) is arctan (x). But since i'd like to know arctan (x), could someone please help me to find the intergral in terms of x (non-trigonometric). Sep 20, 2011 #13 tiny-tim NettetNote that 1 + x 2 = 1 4 ( t 2 + 2 + 1 t 2). So 1 + x 2 = 1 2 ( t + 1 t). That was the whole point of the substitution, it is a rationalizing substitution that makes the square root simple. Also, d x = 1 2 ( 1 + 1 t 2) d t. Carry out the substitution. "Miraculously," our integral simplifies to ∫ d t t. Share Cite answered Aug 5, 2012 at 15:26

Nettet11. okt. 2024 · Solve the indefinite integral of 1/sqrt (x^2+2x+5). I solved it all out by completing the square and then trig sub and then drawing a triangle to go back to x variable and got: ln (sqrt (x^2+2x+5)/2 + (X+1)/2 ) but the book answer is: ln (sqrt (x^2+2x+5) + x + 1 ) So, how did they rid of the 1/2 or where did I go wrong?
