Question

Find the value of the sec 19° using your calculator.
Answer
0.989
0.946
1.058
1.011

Answer 1

my calculator only does division by primes ....

Answer 2

\[cos(x)=1-\frac{1}{2!}x^2+\frac{1}{4!}x^4-\frac{1}{6!}+x^6-\frac{1}{8!}x^8...\]

but youd have to convertdegrees into radians; 19*pi/180 and us it for x

then flip the results to get a sec

Answer 3

opps, got a typo :)

\[cos(x)=1-\frac{1}{2!}x^2+\frac{1}{4!}x^4-\frac{1}{6!}x^6+\frac{1}{8!}x^8...\]
thats better
