HELP ME PLEASE i'll love u forever and give u brainliest

hey

Step-by-step explanation:

1st one is is not one one

reason: all trignometric functions are not one one and onto

So all the domains in trignometric ratios becomes range in inverse trignometry

2nd one is (-π/2,π/2)

see this is the range of tan inverse x whereas it is the

domain for tanx

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
