Webbsec (x) / csc (x) is equivalent to (1/cos (x)) / (1/sin (x)) and by multiplying by the denominator's reciprocal, you get sin (x) • 1/cos (x), or sin (x) / cos (x). This simplifies … WebbA) secx cscx B)1+cotx C)sinx tanx D)-2tan^2x. 3 answers; Precalculus; asked by Anne; 523 views; Perform the multiplication and use the fundamental identities to simplify.

Rewrite in terms of sines and cosines, then cancel the common factors. 5. How do you prove (1+sinx)/ (1-sinx)= (secx+tanx)^2? In proving identities, always start from a more complex side. ( sec x + tan x ) ² = ( 1 / cos x + sin x / cos x) ² since sec x = 1 /cos x and tan x = sin x / cos x in company 3.0 pre intermediate answer key
