sec (\frac{3.14}{2})

1255.76598 \dots

求解步骤

sec (\frac{3.14}{2})

数字相除:

\frac{3.14}{2} = 1.57

= sec (1.57)

sec (1.57) = 1255.76598 \dots

= 1255.76598 \dots

e x p an d \frac{10 ( 13 - 2 )}{3}

e x p an d (x - \frac{3}{2})^{\frac{3}{4}}

e x p an d \frac{4 ( 3 - x ) ^{4}}{81}

e x p an d \frac{( x \cdot e ^{x} )}{( ( x + 1 ) ^{2} )}

e x p an d \frac{1}{( 1 - \frac{a}{x} ) ^{3}} - \frac{1}{( 1 + \frac{a}{x} ) ^{2}}
