01- Seja x um ângulo do primeiro quadrante (ou seja: 0° < x < 90° ). Sabe-se que sen x = 0,2021 e deseja- se determinar o valor de tan x.
a) Primeira solução: calcule cos x = \sqrt{1 - \: se n { \:}^{2} x} e depois calcule tan x = \frac{sen \: x}{cos \: x}
b) segunda solução: calcule x = asen (0, 2021) é depois calcule tan x.
