 # Tensor product function
-The tensor product function is defined as:
-``f(x) = \prod_{i=1}^d \cos(a\pi x_i)``
+A tensor product function combines multiple functions or vectors using the tensor product operation. The tensor product is a mathematical operation that takes two vectors and produces another vector space, capturing their joint behavior across multiple dimensions.
+
+For instance, consider a tensor product function defined as follows:
+
+```\[ f(x) = ∏ᵢ=₁ᵈ cos(aπxᵢ) \]```
