Find the exact value of cot(7pi/4) Solution As we have cot(7π/4) We can write it as cot (2π – π/4) = cot (8π – π) / 4 = cot (7π/4) {7pi/4 lies in the 4th Quadrant} Therefore cot (2π – π/4) = cot π/4 { cot (180° – θ) = – cot θ } = 1 Similar Questions Question 1 Find the exact value of sin(7pi/4) Solution As we have2 One may also ask, what is the exact value of CSC 5pi 4?The exact value of cot(π3) cot ( π 3) is 1√3
