Cosine, tan csc??????

Question

sec=2

find sin and tan??

tan=4

find sin and cos??

Answer 1

sec=1/cos=2

cos=1/2

sin=sqrt(1-cos^2)=sqrt(3)/2

tan=sin/cos=sqrt(3)

tan=sin/cos=4

sin=4*cos

sin=sqrt(1-cos^2)

1-cos^2=(4*cos)^2=16*cos^2

1=17*cos^2

cos=sqrt(1/17)

sin=4*cos=sqrt(16/17)

BTW, what does this question have to do with botany?

Answer 2

sec = 2

1/cos = 2 (sec = 1/cos)

1 = 2cos

cos = 1/2

X = 60, 300

sin 60, 300 = [root 3]/2, -[root 3]/2

tan = 4

cant get exact, use arctangent and you will have both answers.
