Answer:
Step-by-step explanation:
We are given four sets of relations as
A function is a relation in which every element in the first set has a unique image in the second set.
Let us check this aspect to A.
This is a function
Now come to B. 3 has two images 4 and 6. so not a function
Next is C. in C 1 has two images 0 and 6. So not a function
For D, 3 has 4 images so not a function.
The value of sin(80°)cos(20°) – cos(80°)sin(20°) using the trignometry property is √3/2.
<h3>What is difference formula in trignometry?</h3>The difference formula in trignometry for the sine funciton is given as,
The trignometric equation given in the problem is,
Compare this equation with the above eqution, we get,
Thus, this equation can be written as,
Hence, the value of sin(80°)cos(20°) – cos(80°)sin(20°) using the trignometry property is √3/2.
