1. Selesaikan integral dibawah ini, dengan terlebih dahulu mengubah urutan integralnya: ∫ 0 1 ∫ 3 y 3 e x^2 dx dy 2. Selesaikan: (^) ∫ 0 1 ∫ 1 2 y ∫ 0 x ( x + 2 z ) dz dx dy 3. Hitung nilai determinan dari B =
4. Dketahui : A =
Tentukan invers dari matriks A
5. Berdasarkan soal nomor 4 diatas, buktikan bahwa matriks A dikali dengan inversnya, menghasilkan matriks Identitas (A x A-1^ = I). 6. Tentukan nilai a, b dan c dari sistem persamaan linier : a + b + 2c = 5 a + 2b – c = 4 a + 3b + c = 8 7. Selesaikan PD : dy dx
y + 9 x + 5
8. Tentukan penyelesaian dari PD dibawah ini jika eksak: (2xy - 3x^2 ) dx + (x^2 + 2y) dy = 0 ======================================================================
