It is known that x belongs to. 0 to 2. What is the range of SiNx + cosx of function y = root 3 times The answer should be - 1 to root 3. I feel that the following two are not right. Who can tell me

It is known that x belongs to. 0 to 2. What is the range of SiNx + cosx of function y = root 3 times The answer should be - 1 to root 3. I feel that the following two are not right. Who can tell me

Y = SiNx + cosx of root 3 times
=Sin of root 3 times root 2 (x + 4)
Because x is. 0 to 2
So the X + 4 group belongs to the 4 / 4 group to the 3 / 4 group
Sin (x + 4) belongs to the root 2 to 1
The range is root 3 to root 3 times root 2
