Simplify this expression. Trigonometry

Step-by-step explanation:

We know that,

sec²x-tan²x=1

sec²x=1+tan²x

Therefore, csc²(π/2-x)/1+tan²x

= sec²x/sec²x

=1

1

Step-by-step explanation:

Sin(90-theta) = cos(theta)

Cosec(90-theta) = sec(theta)

Cosec²(pi/2 - theta) = sec²(theta)

1 + tan²(theta) = sec²(theta)

sec²(theta)/sec²(theta) = 1

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

    200 words per minute

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
