DIFFERENCE IDENTITIES sin(x - y)=sin(x) cos(y) - cos(x) sin(y) cos(x - y) = cos(x) cos(y) + sin(x) sin(y) tan(x) ... 1. 1 y = tan(x) y. For Jupiter-like atmospheres, this ratio is ≪1 for planets around very low mass M dwarfs and ≳1 when the stellar mass is greater than about 0.6 solar mass. 1/(1 + sin2 x) is best integrated using u= tanx. The ke y to the automatic ... one of the substitutions listed in table 1. The choice will be based on ... 9₁ (1) = 4(1)³² + 3 (1) ² 4(1) = 30 (UN STABLE) (N=1) g'(0) = 0, 9" (N) ... → du = secx tanx, v=tanx). = secxtanx - S secx. S secx tan² x dx. = secx tanx ...

E.g.f.: (1/x)*Series_Reversion( x*(1-tan(x)) ). a ... 1/(1 - tan(x)) begin: G^1: [(1), 1, 2, 8, 40, 256, 1952, 17408 ... Apr 1, 2012 ... I=∫ (tanx*(tanx)' dx). let u=tanx. I= ∫(u dx). =c+1/2 * u2. =1/2 tanx2+c. what to do: Isolate a factor sec2x and denote u=tanx. B2: n is odd. I ... Mar 11, 2008 ... 1 = tan x + sec x = (sin x + 1)/cos x = (-cos(pi/2 + x) + 1)/sin(pi/2 + x) = 2sin²(pi/4 + x/2)/(2sin(pi/4 + x/2)cos(pi/4 + x/2)) = tan(pi/4 + x ... Sep 1, 2011 ... i.e. tanx = 1. This means (in this interval) that x = π/4. So π/4 is the only critical number. This means we have to check the points 0, π/4 ...
