Question

can anyone sketch f(x)= sec theta/2

Answer 1

http://wolframalpha.com can do that.

Answer 2

it would be great if you could show me how to arrive at the values

Answer 3

You could just input this:
f(x) = (secx)/2

Answer 4

ok

Answer 5

Answer 6

go and download geobegra

http://www.geogebra.org/cms/

it graphs everything

Answer 7

Actually, the function should be:\[f(\theta) = {\sec \theta \over 2} \]OR\[ f(x) = {\sec x \over 2}\]

Answer 8

\[f(x) = {\sec \theta \over 2} \]This does not make sense.

Answer 9

place the sec before the fraction so you get sec*0/2

Answer 10

make that sce*theta/2

Answer 11

i'll try typing correctly again sec*theta/2

Answer 12

\[\sec\frac{\theta}{2}=\frac{1}{\cos\frac{\theta}{2}}\]
