Tan^2 + sec^2 = 1
Tan^2 + sec^2 = 1-Step 1 tan 2 x Simplify ————— xsec 2 Canceling Out 11 Canceling out x as it appears on both sides of the fraction line Equation at the end of step 1 tan 2 1 ———— sec 2 Step 2 Rewriting the whole as an Equivalent Fraction 21 Subtracting a fraction from a whole Rewrite the whole as a fraction using sec 2 as the denominator(2) 1 = cot(a) The left side is more complicated so start there tan(a) sec2(X) 1 = tan(x) Use a Pythagorean identity on the denominator = tan(3) Now you have = 2 Cancel = Now you have 3 Use a reciprocal identity

We have 1tan 2 = sec 2 1(3/4) 2 = sec 2 1(9/16) = sec 2 sec 2 = (169)/16 = 25/16 Taking square root on both sides sec = 5/4 We have cos = 1/sec cos = 1÷(5/4) cos = 4/5 Hence sec = 5/4 and cos = 4/5 3 If cot = 40/9 , find the values of cosec and sin Solution Given cot = 40/9 We have 1cot 2 = cosec 2We get (tan(x))2 1 = (sec(x))2 1 = (sec(x))2 (tan(x))2 Now, we will see if 1 = (sec(x))2 (tan(x))2and 1 = (sec(x))2 (tan(x))2 can both be true We can do this by assuming that they are both true, and then add the equations to get 2 = 2(sec(x))2 1=(sec(x))2Find all solutions of sec^2xtan^2x=3 in the interval 0,2piSince tan^2 = sec^2 1 you getsec^2 sec^21 = 3 2sec^2= 4 sec^2 = 2
