Question

2. Value of sec 26°-cot 64° is​

Answer 1

Answer:

1

Step-by-step explanation:

{ \cot}^{2} 64 = { \tan}^{2} (90 - 64) ={ \tan }^{2} (26)cot

2

64=tan

2

(90−64)=tan

2

(26)

Using this value above,

{ \sec}^{2} 26 - { \tan }^{2} 26sec

2

26−tan

2

26

Using identity,

{ \sec}^{2} \alpha - { \tan }^{2} \alpha = 1sec

2

α−tan

2

α=1
