Web10 apr. 2024 · By substituting the value of tan θ + sec θ = 4, in the above equation, we get ⇒ sec θ – tan θ = 1/4 ... (2) Adding equation (1) and (2), we get ⇒ 2 sec θ = 17/4 ⇒ sec θ = 17/8 cos θ = 8/17 Mistake Points It is tan θ which is equal to 15/8. The above two equations that we solved were: tan θ + sec θ = 4 sec θ – tan θ = 1/4 Download Solution PDF Webwhich has the roots $\tan \left(\frac{2\pi}{7}\right)^2 ,\tan\left(\frac{4\pi}{7}\right)^2$ and $\tan\left(\frac{2\pi}{7}\right)^2$ Getting further equations where roots will be square of the current roots is easy, but going back to find square roots is a bit ambiguous for me, I'd like to know if there is a better way. I did it like this:
