WebbThe value of tan 75°=2-root3It`s very easy and simple just the thing is you have to remember the formula. I will say you in a easy and simple methodThe value of cot … Webb29 maj 2024 · If tan + sin = m and tan – sin = n, then prove that m 2-n 2 = 4 sin tan. Sol:We have, tan + sin = m (i) And tan -sin =n (ii) Now, m + n = 2 tan And m – n = 2 sin. (m + n)(m -n) = 4 sin 6 tan m 2-n 2 ... general solution is θ = 7π/4 + 2 n π, n∈ Z. Q17.
