Question

is it correct sin²Theeta × cos²theeta = 0
Please solve it . ​

Answer 1

Answer:

Yes

Step-by-step explanation:

If Sin²theta × Cos²theta=0

Then one component should be 0

That is if theta = 90°

or theta equals 0°

Answer 2

so i will take Ф as theeta

so,

sin2Ф *cos2Ф =0

LHS

cos2Ф-1 * cos2Ф
