Verify each trigonometric equation by substituting identities to match the right hand side of the equation to the left hand side of the equation. 1) cot x sec4x = cot x + 2 tan x + tan3x

2) (sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x

3) 1 + sec2x sin2x = sec2x

sine of x divided by one minus cosine of x + sine of x divided by one minus cosine of x = 2 csc x

- tan2x + sec2x = 1

step by step please

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

inverse property is the answer
