How do you put sec cubed in a calculator?

Answer 1

sec x = 1/cos x

→ sec³ x = 1/cos³ x

or sec³ x = (cos x)^-3

Therefore to enter sec³ x on a calculator:

Newer, "natural" calculators:

mathio: sec³ x → [x-power] [cos] [<angle>] [)] [navigate →] [(-)] [3] [=]

lineio: sec³ x → [(] [cos] [)] [)] [x-power] [(-)] [3] [)] [=]

Older, function acts on displayed number calculators:

sec³ x → [angle] [cos] [x-power] [3] [±] [=]
