You can integrate tanθ
write tanθ=sinθ/cosθso now, integral of tanθ.dθ=integral of sinθ/cosθ.dθ→1put cosθ=t→2there fore -sinθ.dθ=dt→3put 2 and 3 in 1so,the question becomes integral of tanθ.dθ=integral of -dt/t→4=-log t +c → 5 [reason:dx/x=logx]put 2 in 5, =-log cosθ+Cwhere C is the integration constant

I need help to understand: fxx for f(x,y)=x^2+y^2-2xy
Need help figuring perimeter and area.
Differentiate following functions. (a) f ( x ) = 15x 100 - 3x 12 + 5x - 46 (b) h ( x ) = x π - x √2 Solution (a) f ( x ) = 15x 100 - 3x 12 + 5x - 46 I
In the earlier section we modeled a population depends on the assumption that the growth rate would be a constant. Though, in reality it doesn't make much sense. Obviously a popula
Your friends have opened an ocean fishing operation that requires their fishing vessel to cross a channel, where the depth of the water (measured in metres) varies with time, and i
yes you can intergrate tan θ tan q = sin q/cos q (1) let, y = cos q so, dy/dq = -sin q this implies, dq=dy/-sin q (2) putting values in (1) ∫ 1/-y = -log|y| =-log|cos q| so the ∫ tan q = -log|cos q|
yes you can intergrate tan θ
tan q = sin q/cos q (1)
let,
y = cos q
so, dy/dq = -sin q
this implies, dq=dy/-sin q (2)
putting values in (1)
∫ 1/-y
= -log|y|
=-log|cos q|
so the ∫ tan q = -log|cos q|
