The formula to find the sum of the first n terms of our sequence is n divided by 2 times the sum of twice the beginning term, a, and the product of d, the common difference, and n minus 1. The n stands for the number of terms we are adding together.
sin(3)+cos(3)sin(3)tan(3)3=0=−cos(3)=−1=−4+,∈ℤ=−12+3
sin(3x)+cos(3x) =0 sin(3x) =−cos(3x) tan(3x) =−1 3x =−

Answer:
1/6
Step-by-step explanation:
There are 6 different outcomes when rolling a fair dice.
You can roll a:
1
2
3
4
5
or
6
There is one outcome we want. Probability=number of desirable outcomes/total number of options.
1= number of desired outcomes
6-=total number of outcomes
