Question

Simplify the following trigonometric expressions:

(sin x – cos x)(sin x + cos x)

Answer 1

hint: difference of two squares \[(a+b)(a-b) = a^2 - b^2\]

Answer 2

thanks @Igbasallote

Answer 3

LGBASALLOTE* heh

Answer 4

sorry

Answer 5

By any chance do you know how to solve these
. tan x(cos x – csc x) (sin x + cos x)(sec x+csc x)

Answer 6

can you type it out? copy-pasting leads to uhmm visual errors

Answer 7

yup
#1) tan x(cos x – csc x)

#2)(sin x + cos x)(sec x+csc x)
these are two different problems

Answer 8

im not sure...try asking it as a new question so others can help :)
