WebSolution: If the principal value of sec − 1 x is α then we know, 0 ≤ θ ≤ π and θ ≠ π 2 . Therefore, If the principal value of sec − 1 (1) be α then, sec − 1 (1) = θ. ⇒ sec θ = 1 = sec 0 [Since, 0 ≤ θ ≤ π] Therefore, the principal value of sec − 1 (1) is 0. 6.

Webcos θ = cos ( θ + 2 π n) where n ∈ Z. and then by method of contradiction, I have proved π can't be period of the cosine function. Hence 2 π is the principle period of cosine function. Similarly, I have shown 2 π is the principal period of the sine function. In my textbook, it is written “For the time being we shall assume that the ... WebMay 27, 2016 · cosθ = base hypotenuse = b l. These are the two most basic trigonometric functions from which other four basic trigonometric functions tanθ, secθ, cosec θ and cot θ are derived, tanθ = height base = h b = sinθ cosθ, it is the ratio of the two primary functions. secθ = hypotenuse base = l b = 1 cosθ, it is just the inverse of cosθ. oliver hoffmann foundation
