How does the matrix tanning bed work?

ive been using the matrix bed for almost 2 years now. its the most amazing tanning bed ive used by far. i can tan in this bed after not tanning for six months and not burn at the full time. i have very fair skin and notice a nice tan after just one session. Actually, the matrix is very different than other tanning beds. It is made so that you receive 99% UVA rays and 1% UVB rays, approximately. The UVB rays are the rays that burn you, while the UVA rays allow you to tan. Also, it allows you to continue tanning for 48 hours, after laying in the bed. While all rays can be harmful, the ones you should protect against the most are UVB. Please don't take that to mean that this bed won't or can't cause skin problems/cancer. Any sunlight, in excess, can and will do harm, but this bed is much less likely to cause harmful skin problems than many other beds.


Which is greater tan 1tan2 tan3 .arrange them in descending order?

If the angles are measured in degrees or gradians, then: tan 3 > tan 2 > tan 1 If the angles are measured in radians, then: tan 1 > tan 3 > tan 2.


What is tan20tan32 plus tan32tan38 plus tan38tan20?

Oh honey, you're throwing some trigonometry at me? Alright, buckle up. The sum of tan20tan32 plus tan32tan38 plus tan38tan20 is equal to 1. Just plug in those values and watch the magic happen. Math can be sassy too, you know.


How can arccot of tanx be simplified?

There is not much that can be done by way of simplification. Suppose arccot(y) = tan(x) then y = cot[tan(x)] = 1/tan(tan(x)) Now cot is NOT the inverse of tan, but its reciprocal. So the expression in the first of above equation cannot be simplified further. Similarly tan[tan(x)] is NOT tan(x)*tan(x) = tan2(x)
