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

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

there is no answer sorry!
