Step-by-step explanation:
Using the Pythagorean identity
sin²θ + cos²θ = 1 ( divide terms by sin²θ )
+
=
, that is

Step-by-step explanation:
|-2x| = 4
There are two solutions, one positive and one negative
-2x = 4 and -2x = -4

-2x/-2 = 4/-2 -2x/-2 = -4/-2
x = -2 and x = 2
Answer:
Percent error: 6.00%
Step-by-step explanation:
We find the mean of the three masses
Mean = 1.20 + 0.91 + 1.08 / 3
Mean = 1.06 kg
The experimental value of mass is = 1.06 kg
The actual value of mass = 1 kg
The percent error is: (experimental value - actual value/actual value)*100
Percent error : (1.06 - 1 / 1)*100
Percent error: 6.00%
