Question

Prove that
sin 0 -cos O +1/
sin 0 + cos 0 - 1=1/
sec 0 - tano​

Answer 1

Hence it is proved that,

sin 0 -cos O +1/

sin 0 + cos 0 - 1=1/

sec 0 - tano​

Given,

sin 0 -cos O +1/

sin 0 = 0

cos = 1

∴ sin 0 - cos 0 = 0 - 1 = -1

sin 0 + cos 0 - 1=1/

sin 0 = 0

cos = 1

∴ sin 0 + cos 0 = 0 + 1 = 1

sec 0 - tano​

sec 0 = 0

tan 0 = 1

∴ sec 0 - tano = 1 - 0 = 1
