Seja !$ f \mathbb{ R} \rightarrow IR !$ definida por !$ f(x) = { \begin{cases} -3x + a,se\,x\ge 0\\3x^2 - x + b,\,se\,x < 0 \end{cases}} !$

Se f(1) = 1 e f(−1) = 8, então .

Dadas as matrizes !$ A = { \begin{pmatrix} a\,\,-b\\b\,\,\,\,a \end{pmatrix}} !$ e B = A², o valor do determinante de B é .

Se 4 é uma das raízes do polinômio P(x) = x³ − 8x² + 19x − 12, então as outras raízes são números

Se f(x) = 3senx e g(x) = cos2x, com x real, então o valor de !$ f { \begin{pmatrix} { \large 3 \pi \over 2} \end{pmatrix}} + g { \begin{pmatrix} { \large \pi \over 2} \end{pmatrix}} !$ é .
