trigonometric functions state that cosine functions are even so that automatically rules out the first two options.

sine functions are odd so the last two are right.

odd functions: f(-x)=-f(x)

so the sine would be: sin(-x)=-sin(x)

the third option should be the right answer

Find an equation for the plane through the points p=(0,0,0), q=(0,1,0), and r=(1,2,3)
jek_recluse [69]
Hello,

Assume Ax+By+Cz+D=0 the plane 's equation.

p=(0,0,0)==>A*0+B*0+C*0+D=0==>D=0

q=(0,1,0)==>A*0+B*1+C*0+0=0==>B=0

r=(1,2,3)==>A*1+0*2+C*3+0=0==>A=-3C
Let C=1==>A=-3

An equation of the plane is -3x+z=0
