If cosθ=7/25, write the value of (tanθ+cotθ)

  • 0

Sir please give me a detailed solution of this question as it is already asked in previous year paper of 2008 in which we have given that cosθ=7/25, we need to find the value of (tanθ+cotθ) by using basic  trigonometric formulas

  1. cosA=7/25

    Therefore,

    Base =7 and Hypotenuse =25

    Therefore, Perpendicular =√25²=√62549
    =√576
    =24

    Hence,
    tanA+cotA
    =24/7 + 7/24
    =(576+49)/168
    =625/168
