no1. tatau..hehe
no.2
a) u.v = (1)(3)+(2)(5)+(-3)(2) = 7
b) cos a = u.v / |u||v|
|u| = punca kuasa dua ((1^2)+(2^2)+((-3)^2)) = punca kuasa dua (14)
|v| = punca kuasa dua ((3^2)+(5^2)+((2)^2)) = punca kuasa dua (38)
so...
cos a = 7 / (punca kuasa dua (14))x(punca kuasa dua (38)) = 0.3035
a = 72.33 darjah |

adoi..tetibe ade lain mende nak wat
jap..wat dulu..
no 1. a) N={6,8,11,13,15,17,19,20,22,24,26,28,31,33,35,37,39,40,42,44,46}

3.
csc (x) dy = -y dx ; csc x = 1/sin x
thus, -1/y dy = sin x dx <<<integrate both side
- (ln y) = -cos x + C
ln y = cos x + C << applying the exponential both sides
y = e^(cos x + C)
y = e^(cos x) + C
b..tak ingat... |
