- Q1Los op voor x: 2sin(x) + √3cos(x) = 0x = 150 graden of x = 330 gradenx = 120 graden of x = 300 gradenx = 90 graden of x = 270 gradenx = 60 graden of x = 240 graden30s
- Q2Als sin(a) = 1/2 en cos(b) = 1/2, wat is dan sin(a+b)?1/2√2/21030s
- Q3Wat is de som en verschil formule voor sinus en cosinus?sin(a+b) = sin(a)cos(b) + cos(a)sin(b) en cos(a-b) = cos(a)cos(b) + sin(a)sin(b)sin(a+b) = sin(a)cos(b) - cos(a)sin(b) en cos(a-b) = cos(a)cos(b) - sin(a)sin(b)sin(a+b) = sin(a)sin(b) - cos(a)cos(b) en cos(a-b) = cos(a)cos(b) - sin(a)sin(b)sin(a+b) = sin(a)sin(b) + cos(a)cos(b) en cos(a-b) = cos(a)cos(b) - sin(a)sin(b)30s
