Answer:
Step-by-step explanation:
In the picture.
I hope that it's a clear solution.
You need to first make denominator in the fractions you have equal, then simply subtract numenators.
example:
2/3 - 1/2
first step is to make denominators equal.
for this example, the denominator will be equal to 6 which is 2x3
so, 2/3 = 4/6 and 1/2 = 3/6
so, the expression now becomes:
4/6 - 3/6
simply subtract numenators and the denominator will be 6 as well.
4/6 - 3/6 = 1/6
another example:
3/4 - 1/2
here the denominator can be equal to 4 in all terms
1/2 = 2/4
so, the new expression is now:
3/4 - 2/4 = 1/4
The 2nd option is the answer :)!
Use cos sin and tan and looks up rules of cos sin tan and it will show you the rules and use those methods to plug into your equation
The correct answer is 6*10^-6 ..........................
