$\cot\ \left(90\degree-A\right)=$  

In a right angled triangle the side opposite to right angle is called

 $\sin^229\degree+\sin^261\degree=$  

 $\sin\theta=\frac{4}{3}\$  for some angle of  $\theta$  . State true or false

 $\sec^260\degree-1=$  

Write the maximum value of $\sin\theta$  

State true or false: Two angles are said to be complementary if their sum is $90\degree$  

State true or false $\cos\theta=\frac{base}{hypotenuse}$  

Value of  $\cos45\degree$  is

 $\sin\ \left(90\degree-A\right)=$  

 $\sin\ \left(90\degree-\theta\right)=$
