Question

if sec A =root 2 then find the value of 3 multiply cos square a+5multiply tan square A divided by4 multiply tan square A subtract son square A

Answer 1

If secA is root 2 then sec 45 is root two so A's value is 45.....so we know cos 45 is 1/root 2 , tan45 is 1, sin 45 is also 1/root 2...so on substituiting these values we will get on to a conclusion that 3/2+5 divided by 4-1/2.....so on further solving this we will get an answer 13/7.......

Hope this helped you...and i hope that the answer is also correct :)
