-e^{cos(pi)}-(-e^{cos(0)})

- e^{c o s (π)} - (- e^{c o s (0)})

- \frac{1}{e} + e

Solution steps

- e^{c o s (π)} - (- e^{c o s (0)})

Use the following trivial identity:

cos (π) = (- 1)

Use the following trivial identity:

cos (0) = 1

= - e^{- 1} - (- e^{1})

Simplify

- e^{- 1} - (- e^{1}) : - \frac{1}{e} + e

= - \frac{1}{e} + e

1 + tan^{2} (31 5^{\circ})

- cos (4 \frac{π}{2})

arctan (\frac{16}{32})

- 2 (3.27) - e^{- 0.54} sin (3.27)

2 \cdot cos (\frac{3 π}{2})
