Question

If sec theta minus tan theta equal to x show that sec theta equal to one divided by x bracket x plus one divided by x bracket close and tan theta eqaul to one divided by x bracket one divided x minus x bracket close

Answer 1

Answer:

Step-by-step explanation:

1/2(x+1/x)

=1/2[(sec theta-tan theta)+1/sec-tan]

1/2[ (sec-tan)+sec²-tan²/sec-tan]

1/2[sec-tan+(sec+tan)(sec-tan)/sec-tan]

1/2[2sec]

Sec

Same for RHS we get

tan theta

LHS
