Question

Find the value of tano
sino
cos o
+
sino.cos e​

Answer 1

Answer:

Step-by-step explanation:

r 0, 30,45, 60 and 90 degrees

sin 0 = cos 90

sin 30 = cos 60

sin 45 = cos 45

sin60 = cos 30

sin 90 = cos 0

tan 0 = sin 0 / cos 0 = 0/1 = 0

tan 30 = sin 30 / cos 30

tan 45 = sin 45 / cos 45

tan 60 = sin 60 / cos 60

tan 90 = sin 90 / cos 90 = 1/0 which is NOT DEFINED

Similarly, we have sec  = 1/cos , cot  = cos  / sin  and cosec  = 1/ sin
