Trig Verify-Simplify

100

Verify this equation, pretty please.

(1+tan²x)/sec²x = 1

1 + tan²x = sec²x

sec²x = sec²x

sec²x/sec²x = 1

GOOD JOB IF YOU GOT IT!!!!

200

Verify.

(1-cos2x)/2 =sin²x

cos2x = 1 -2sin²x ---> 1 - cos2x = 1 -(1-2sin²x)

= 2sin²x = (1-cos2x)/2 =sin²x

300

Verify

(cosx)/(1-sinx) + (cos2x)/(1+sinx) = 2secx

Trig solving

100

2cos²(x)-1=1

x= 0, pi/2, pi

200

4tan(x)/2-2tan²(x)=0

x=0, 2/pi, pi

300

sin(pi/2 - x)² - cos(pi/2 - x)² = 1/2

x= pi/6

400

cos(2x) - cos²(x) = 0

x= 0, pi, 2pi

500

cos(x) - sin(x)=1

x= 0, pi/2, pi
