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
Callie's grandmother pledged $0.50 for each mile Callie walked in her walk-a-thon. Callie walked 9 miles. How much does her grandmother owe? Multiply the number of miles (9) th
ABC is a right triangle right-angled at C and AC=√3 BC. Prove that ∠ABC=60 o . Ans: Tan B = AC/BC Tan B = √3 BC/BC Tan B =√3 ⇒ Tan B = Tan 60 ⇒ B = 60

A number of the form x + iy, where x and y are real and natural numbers and is called as a complex number. It is normally given by z. i.e. z = x + iy, x is called as the real part
parts of matrix and functions
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|

∫ 1/-y
= -log|y|
=-log|cos q|
so the ∫ tan q = -log|cos q|
