Question

i need help one his problem

Answer 1

Where is the problem?

Answer 2

\[\cot \alpha+\tan \alpha=\csc \alpha \sec \alpha \]

Answer 3

over the internal from 0 is less than alpha and less than 2 pie

Answer 4

A all real number
b all reals except multiples of 0 and pie
c all reals except multiples of pie/2 and 3pie/2
d all reals except multiples of quadrantal angles

Answer 5

cotA+tanA
= cosA/sinA+sinA/cosA
=(cosA)^2+(sinA)^2/sinA*cosA
=1/sinA*cosA
=cosecA.secA

Answer 6

ok

Answer 7

wait so which one would it be ?

Answer 8

what?

Answer 9

i meant which choice is correct

Answer 10

oh... wait

Answer 11

It should be B... Because cosec(180degree Or pi)=undefined and sec( 0 degree) = undefined

Answer 12

okay thank you :))))

Answer 13

can I ask another question? :)

Answer 14

yeah sure

Answer 15

how many solutions are there to the equation if 0<x<pie
