Secx =root29/2
Root upon secx+1/secx-1=root upon root29+2/root29-2
Root upon secx+1/secx-1=root upon root29+2/root29-2

bro tanx = 5/2 so , opp/adj = 5/2 so hyp = 25+4 (pythogorus theorem)
root 29 so sec = hyp / adj = root 29 / 2
and you must know sec (x+1) / sec (x-1) becomes tan^2x
so tan^2 (2 * root 29 / 2) ===> so root 29 ^ 2 = 29
root 29 so sec = hyp / adj = root 29 / 2
and you must know sec (x+1) / sec (x-1) becomes tan^2x
so tan^2 (2 * root 29 / 2) ===> so root 29 ^ 2 = 29
