Question 20

kaj velja za kotne funkcije komplementarnih kotov

Answer 20

α + β = 90°
sin α = cos β
sin β = cos α

Question 21

cos ( α - β)=

Answer 21

= cos α cos β + sin α sin β

Question 22

cos (α + β)=

Answer 22

= cos α cos β - sin α sin β

Question 23

sin (α + β)=

Answer 23

= sin α cos β + sin α cos β

Question 24

sin (α - β)=

Answer 24

= sin α cos β - sin α sin β

Question 25

tan (α + β)=

Answer 25

1 - tan α tan β

Question 26

tan (α - β)=

Answer 26

1 + tan α tan β

Question 27

sin 2α =

Answer 27

= 2 sin α cos α

Question 28

cos 2α =

Answer 28

cos^2 α - sin^2 α

Question 29

tan 2α =

Answer 29

1 - tan^2 α

Question 30

cos 3α =

Answer 30

4 cos^3 - 3 cos α
