Answer:
Formula:(from trigonometry)
Tan(A+B)=(tanA+tanB)/(1-tanA*tanB)
Let A=22 degrees,B=23 degrees
Tan(22+23)=(tan22+tan23)/(1-tan22*tan23)
From trigonometry we know tan45=1
Therefore tan(45)=1=(tan22+tan23)/(1-tan22tan23)
=> 1-tan22tan23=tan22+tan23
=> tan22+tan23+tan23tan22 =1
Hence proved
Answer:
$6
Step-by-step explanation:
6 x 4 = 24
Answer:
Step-by-step explanation:
-(-1) is 1 because if you multiply by a negative number becomes positive
so
it is 1 unit to the right of 0
Answer: It is 3 and negative -3
Step-by-step explanation:3 units away from zero forwards and back are both 3 but one is negative
